How does pion exchange cause protons and neutrons to be attracted to each other? [duplicate]
I read that neutron and protons are attracted through exchanging pions between each other. However, as far as I understand, they are just exchanging a meson, not any force carriers. What causes them ...

What is the significance of the Strong interaction between a pair of Neutrons?
When we are introduced to the Strong Nuclear force, we are told that it prevents the nucleus from flying apart because of the electric repulsion between protons. But there is no such repulsion between ...

The difference between neutron and proton separation energy of a nucleus
For a given nucleus, why does the value of the neutron separation energy $S_n$ differ from the value of the proton separation energy $S_p$? One of the reasons that is immediately obvious is that the ...

Why are nuclei with large numbers of neutrons only stable with correspondingly large numbers of protons? [duplicate]
Large numbers of protons need to be separated by neutrons, otherwise they repel....
But why do nuclei with large of numbers of neutrons only remain stable with a relatively, correspondingly large ...

Why spin-aligned nucleons bind stronger together [duplicate]
Protons bind to neutrons only if their spin is parallel to each other. Is there an easy explanation for this? What force is responsable for this spin dependence?

Why doesn't a nucleus-like body made up of just neutrons exist?
We know that neutrons exert short ranged nuclear forces over other nucleons in a nucleus, and these forces are only attractive in nature. Also this force is universal and doesn't differentiate between ...

How can I visualize the oxygen nuclear charge density?
Oxygen has 8 protons and 8 neutrons.
Based on the nuclear shell model, protons should pair with anti-parallel protons to create singlet spin states,
and neutrons should similarly pair with anti-...

Pauli exclusion principle: why does it imply that $Z\approx N$ in stable nuclides with $A<40$?
I have read that when representing the possible nuclides in the $(Z,N)$ plot, the stable nuclei located on the line $N=Z$ for $A<40$, and that this is due to the Pauli exclusion principle.
I have ...

Doesn't the neutron's lack of an electric dipole moment conflict with the concept of baryons having a radius?
The proton radius puzzle appears to one of the more widely known unsolved problems in physics, but doesn't it point to a much deeper issue? Nearly all of a baryon's observed mass can be attributed to ...

Nuclear force and binding energy
What i read about binding energy is that it is the energy released when nucleus is formed due to the attraction of the strong nuclear force between nucleons. But even after the nucleus is formed, the ...

'Forces' enacted by hot neutrons in fusion bomb - Pauli exclusion
Are Pauli exclusion 'forces' on a neutron 100% electromagnetic (Lennard-Jones seems more acute relationship compared to electrostatic force)
If so does that neutrons have two forces between them - '...

Cold fusion with ionized hydrogen and neutron radiation
Would bombarding ionized hydrogen gas with neutron radiation cause cold fusion as the neutrons have no electrostatic repulsion to overcome therefore making it much easier to get within range of the ...

Strong force and radioactivity [duplicate]
Why does adding more neutrons to an atom unstabilise it? Won’t adding more neutrons increase the strong force and thus knit the nucleus more tightly? Or is it because it’s being added in a particular ...

Unstable vs. stable nuclei plotted on a graph
The enclosed graph shows the number of Protons on the x-axis (Z), and the number of Neutrons on the y-axis for all elements (N). Stable combinations are marked by black squares, whereas unstable ones ...
