Hi Nowator,
Can you identify the cause of instability in your model?
Does your method shed any light on why a nucleus consisting of one, three and four He-4 are stable but two are not? This is a puzzle that I was just wondering about.
I thought some of your ideas were interesting, like the substructure of nucleons and the reason for reduced mass.
I have a spreadsheet where I compute what the binding energy of each element would be if it were made up of as many He-4 as possible (contributing only the free He-4 binding energy), then partial He-4 for all the remaining particles including dineutron. The He-4 and partial He-4 account for over 70% of the binding energy per nucleon just using the binding energy for those species when free for all nuclei checked. Can you really have so many unpaired protons and neutrons in your shells? It seems that when you break up a He-4 you lose a lot of binding energy! Here's the sheet: https://drive.google.com/file/…VRm7OxoK/view?usp=sharing
Do you know of Randell Mills' theory? I have been trying to apply it to nuclei, with modest results. Here is a recent effort https://www.ej-physics.org/ind…ejphysics/article/view/10 and here is Dr. Mills' theory https://brilliantlightpower.com/book-download-and-streaming/ He would agree with you that the nuclear forces are electromagnetic, but has a different geometry for his nucleons.
Welcome!
