As in our model the neutron is similar to mini-atom of hydrogen, their properties should be also similar. So, at casual rendezvous with a proton,
the neutron should start to be polarized, and on some distance from a proton, its will transfer to their blanket orbit:
I.e. will enter with it a donor-acceptor bond, known from chemistry.
To determine, where here a neutron and where a proton - now it is impossible.

As a matter of fact, before us a nucleus of deuterium.
Adding now neutrons and protons, it is possible to create all known nuclei of atoms.
The deficit, no less than surplus of , shielding a protons close located in a nucleus, should affect strength of a nucleus, and it will aspire to their some optimum relation by that, or other type of decay.

Similar representation of a nuclear interaction should provide:

And two words about energetics.
As is known, the binding energy of nucleons in a nuclear can reach 8,7 Mev/nucleon. Energy of the orbital in a neutron is equal only 0,78 Mev. I.e. it is much less.
How to be?
In my opinion, as a single decent energy source in a nuclear interaction the spin-spin interaction of protons can serve. I.e., at a nuclear interaction, protons lose a part of the kinetic energy of gyration.
