A Proposed Experimental Test of Repulsion Between Neutrons |
---|
The following are scatter diagrams of the net strong force charge of nuclides plotted versus the neutron number and the proton number. If n is the number of neutrons in a nuclide and p is the number of protons then the net strong force charge of a nuclide is (p−(2/3)n. Below are the scatter diagrams for the net strong force charge of nuclides plotted versus both the neutron and proton number of the nuclide.
The histogram of the net strong force charge of nuclides shows that nuclides are predominantly proton charged. While most nuclides have more neutrons than proton the strong charge charge of the proton is 50 percent greater than that of the neutron and consequently the protons, though smaller in number, outweigh the neutrons in terms of strong force charge.
There are some nuclides which have a negative strong force charge and are thus equivalent to a number of neutrons.

There are many more nuclides with negative strong force charges. Altogether there are 954 out of 2931 nuclides which have a strong force charge of less than zero. If neutrons are projected toward a target of any one of these nuclides they should be scattered by repulsion. Other isotopes of these same elements should scatter neutrons by attraction.
For a clear identification of the nature of the interaction of neutrons with such nuclides there should be an even number of neutrons in the nuclide to avoid combining the effect of neutron spin pair formation with that of the interaction of neutrons through the nuclear strong force. Thus Radium 234 would be an ideal target, as would be Radon 228 also.
