Note on the Interaction of Nuclear Particles

Simple approximate calculations of the ranges and strengths of the interactions of nuclear particles lead to the following conclusions: The interactions are of an exchange nature with the range approximately 2.8×${10}^{-13\mathrm{}}$ cm. The neutron-neutron and proton-proton interactions are approximately equal. The neutron-proton interaction probably depends upon spin orientation. For parallel spins the order of magnitude of the interaction is 40 $m{c}^2$, for antiparallel spins 25 $m{c}^2$. It is further concluded that a di-neutron or di-proton may be dynamically stable, but unstable with respect to $\beta$-decay.
