Meet the principal

There was still a week before departure, so Reiner naturally didn't take any time off.

The day after he invited Claire to travel with him, he came to the laboratory.

Reiner quickly arranged the magic circle that was redeemed from the Magic Association using academic points.

Each of the three particle generation arrays requires thirty academic points. This is different from Fina's father's original array, but an array that has been optimized and improved by several mages. It can produce a pure particle flow without impurities. It is safe and reliable and will not affect the user. Due to the standard magic stone function, usually a three-ring mage can control it independently, and Reiner can naturally use it.

A piece of paper floated next to Reiner, with a sketch of the experiment he designed last night on it.

He first arranged a disc, placed a thin piece of gold foil in the middle of the disc, and then arranged a method on one side of the disc that could generate a particle flow composed of elemental Helios particles with a relative elemental mass of approximately 4. In the array, a microscope is arranged on the periphery of the disk. The disk is surrounded by a receiving screen. If the Helios particle hits the receiving screen, a light spot will be left. This microscope can rotate around the disk, enough to Helios particles were observed coming from all directions.

In order to prevent interference, the entire experimental device was covered by a vacuum glass cover, and Reiner could control the rotation of the microscope through the mechanism.

After assembling the experimental device and debugging it, Reiner officially started the experiment.

He activated the particle generation array, a burst of fluorescence flashed, and the invisible particle stream began to gradually surge, hitting the gold foil.

Reiner set the particle flow release frequency to be very low. After about ten minutes, he stopped the operation of the particle generation array, then turned the microscope to count the landing points of the Hilios particles that fell on the receiving screen.

If we follow Lord Alterac's point of view, the deflection angle of the Xilios particles in this experiment should be very small.

If it hits an electron, based on the mass ratio of the two, the impact of the electron on the Helios particle is minimal and can be ignored.

If an atom is hit, then the positive charges on both sides of the atom cancel each other out, and the Helios particles will have basically no effect.

So, according to the cake-and-raisin model, the Helios particles should have been barely deflected in this experiment and concentrated on the other side of the gold foil.

However, when Reiner finished the statistics, he found that although most of the Hilios particles were concentrated on the side of the receiving screen opposite the particle generation array, there were still a small number of Hilios particles that appeared on the screen. The phenomenon of angular deflection,

The deflection angle of some Hilios particles exceeds 90 degrees, and some are even reflected at 180 degrees!

This goes against the atomic model proposed by Lord Alterac.

Reiner repeated the experiment twice more and obtained similar results. Then he came to the table on the other side, leaned over and started writing.

"...According to experimental phenomena, most of the mass and charge of an atom should be concentrated in a very small space. Atoms are not like cakes studded with raisins, but are surrounded by a very small nucleus. Its electronic makeup.”

Only when the mass of the entire atom is concentrated in a small area can the experimental phenomenon be explained:

Most Helios particles pass through the gaps between atomic nuclei, and even if they hit electrons, they have no effect at all.

A small number of Hilios particles passed through the area close to the atomic nucleus and were repelled by the positive charge, which affected the trajectory of the movement and caused deflection. The angle of deflection increased as the Hilios particles got closer and closer to the atomic nucleus. The bigger.

Some of the Helios particles hit the nucleus exactly and were deflected nearly 180 degrees.

Reiner called this atomic model a nuclear model. He then began to calculate and estimate based on the ratio of Helios particles at various angles on the receiving screen. Finally, he found that compared with the entire atom, the volume of the nucleus was less than 10,000 times its size. First, if the atom is compared to a huge square, then the nucleus is an egg in the middle of the square.

He stopped writing and breathed a sigh of relief.

Reiner didn't end there. He thought about it and wrote down some conjectures at the end:

The first conjecture is that according to the periodic law of elements, although the nuclear charges of elements with similar properties are different, they must have certain characteristics that are similar. Reiner guessed that it is the electron distribution in the outer layer, because according to alchemical reactions, some elements The same number of electrons are always lost in the reaction, which shows that the electrons outside the nucleus are not completely equivalent, and these electrons are different.

The second conjecture is that the atomic nucleus may not be the smallest particle, because the nuclear charge number and relative element mass of the nucleus of different elements are different, as well as the existence of isotopes and the observation by mages that radioactive substances are releasing Xilios A phenomenon in which a particle stream transforms into another element.

Reiner conjectured that there may be a positively charged particle and an uncharged particle. These two particles of the same mass together constitute the atomic nucleus. In this way, every element and even every isotope can be occupied. The theory of a particle is simplified into various atomic nuclei composed of different numbers of two kinds of particles.

He called the charged particles protons and the uncharged particles neutrons.

After writing these two conjectures, Reiner sighed slightly.

At present, with his strength and the level of magic he has been exposed to, he has not been able to verify these two conjectures. Therefore, he does not intend to write these two conjectures into the paper, but retains a trace of selfishness.

Looking up, it was already afternoon. Reiner realized that he hadn't eaten lunch yet, and his stomach seemed to have forgotten his hunger before, and it didn't start to protest until now.

Reiner hurriedly packed up the experimental equipment, put away his notes, hurried to the cafeteria, took a simple meal and ate it happily.

After a full meal, he returned to his office, ready to continue reading "Alchemy" which he had only read the catalog once yesterday.

But when he opened the door, he found that the tiger-striped kitten was already squatting on Reiner's desk, licking his paws, looking quite contented.

"I don't have anything to eat."

Reiner shrugged, put the notes in his arms on the corner of his desk, and gently scratched the kitten's head.

"I'm not here for food today, meow."

"Then what are you here for?"

Reiner asked, and then, after about ten seconds, he suddenly came back to his senses and looked at the tiger striped kitten rubbing his palm with surprised eyes.

"You...you spoke?"

He looked around to make sure that he was not affected by any illusions. He subconsciously took a half step back and stared at the kitten.

"Reintroduce yourself."

The kitten stopped and looked at Reiner with a pair of amber eyes.

"You can call me Lady Freya."
