"Reiner, is there a way to prove your hypothesis?"

Reinhardt's problem is also the concern of other high-level mages, according to Reiner's nuclear structure model, the nucleus has most of the mass of an atom and all the positive charges, but this does not explain why different elements have different nuclear charge numbers and element masses, some theories believe that the nuclei of these elements are unique, but the mages believe that the elements should not be so complex, but should be more concise and basic.

What's more, the phenomenon of radioactivity, elemental decay, also contradicts the assumption that elements have unique nuclei, so several mages are excited to see what Reiner will explain to them.

"That's exactly what I've been working on."

Reiner said, standing up and saluting the other mages, then raised his hand, and a ball of light appeared in the palm of his hand.

David narrowed his eyes slightly, and he saw that this light cluster was not a condensation of magic power, but a circle cluster composed of countless complex magic circles, and the scale of it, according to David's visual inspection, was at least the scale of the top-level spells above the eight rings!

And Reiner only has seven rings.

"This is an auxiliary calculation circle designed by myself to calculate some relatively complex cases."

Reiner said as a projection appeared in the light cluster, revealing a three-dimensional model of the atom.

"First of all, let's look at the basic atomic model, in which the nucleus and the electron are two microscopic particles that are clearly distinguished, and we will temporarily exclude the electron and focus on the nucleus, and now we know that the nuclei of different elements have different nuclear charge numbers and masses, and that under certain conditions, some elements will release rays of the same particle composition as the nucleus of the element Sirius, and at the same time, the elements themselves will gradually transform into other elements with less mass relative to the element, This process we call decay. ”

The atomic model in mid-air begins to diverge, and a particle is separated from it.

"From this radioactive phenomenon, we can put forward a conjecture that the nucleus is not the tiniest particle, but can continue to be divided."

Hearing Reiner's words, Master Hohenheim nodded slightly, he had only been in contact with the theory of microscopic particles for a few weeks, but he could almost understand Reiner's train of thought for the first time.

"And according to what is known so far, the nucleus of the Hydra element has a nuclear charge of 1 and a relative element mass of 1, and if we look at it as an elementary particle, then we can assume that among the particles that make up the nucleus, there is a particle with a positive charge of one unit and a relative element mass of 1, and at the same time, according to the nature of the Hyrios element with two units of positive charge and a relative element mass of 4, we can infer that the nucleus of the Hylios element with two Hydra elements is different from another uncharged particle."

Reiner's explanation is very detailed, but it is not difficult to understand.

"Naturally, we can guess that if the mass of an uncharged particle is the same as that of the nucleus of the element Hydra, then there will be two such particles in the nucleus of the element Sirius, which can also be obtained by studying the isotopes of the element Hydra."

David nodded slightly, Reiner's logic was rigorous, and he couldn't find any obvious mistakes.

"I named the positively charged particle the proton, and the uncharged particle the neutron, the nucleus, which is actually a combination of neutrons and protons."

Reiner's words caused Reinhardt's body to lean forward subconsciously, because the conjecture had penetrated deep into the nucleus, a microscopic realm beyond the reach of mages.

Reiner's conjecture is actually one of the two conjectures that were not included in the paper when Reiner first proposed the nuclear model, and the other conjecture is that the electron configuration inside the elements is not average, but may have certain laws or trajectories, and this conjecture has been verified at the High Council of the Rainbow Tower.

The conjecture of protons and neutrons was limited by the level of magic, and Reiner could not be verified by experiments at that time, but now, Reiner has the corresponding magical strength, so he naturally put it forward.

"Protons and neutrons, very interesting ideas."

Lord Alberton nodded slightly, he touched his chin, thinking about Reiner's words.

If protons and neutrons really exist, then mages will face a huge problem as to why neutrons and protons can be tightly bound in small nuclei.

Uncharged neutrons aside, if protons are really positively charged, then according to current theory, it is impossible to reach such a distance between two protons.

You know, the electromagnetic force between the two protons is much greater relative to the gravitational pull brought about by their masses.

"If this scenario is true, then we do need to find a stronger force that can cause two or more protons to converge in the nucleus without collapsing."

David said that the emergence of one problem is always accompanied by more problems.

"First of all, if we assume that such a force does exist, then we can infer some of the properties of this force from what is now known."

Seeing that the other gentlemen had no objections, Reiner continued.

"First, the strength of this force is very large, at the scale of the nucleus, far exceeding the strength of the electromagnetic force, otherwise it would not be possible to cross the electromagnetic force that exists between the protons and combine it into the nucleus; Second, the distance at which the force works should be quite short, or the decay with the distance is very severe, otherwise the different nuclei will be affected by this force and come together to form a wide variety of elements. ”

Under such assumptions, it is easy for mages to imagine that the protons in the nucleus are bound together by this force, and that, at a certain distance, the attenuating force is balanced by the gravitational force of electromagnetism, so that the nuclei are kept at a fixed distance from each other.

If a special method can be used to eliminate the electromagnetic force between the nuclei, the nuclei can be brought closer together, forming the dense substance like a black pillar seen in the ruins.

The premise of all this is interlocking, and the biggest premise is that the nucleus is indeed divided into charged protons and uncharged neutrons.

"So, Reiner, how do you find a single neutron?"

According to Reiner's hypothesis, the proton is the nucleus of the element Hydra, and the neutron is uncharged, only mass, and difficult to collect with an electric field.

"With rays, ladies and gentlemen, I need extremely high-energy rays."

Reiner looked around and replied.
