If one assumes that the potential energy between protons and neutrons has the shape of a simple potential hole, it is possible from the experimental value of the mass defect of the ${\mathrm{H}}^{2}$, to derive a connection between the mean width and the depth of this curve. This connection proves to be, to a large extent, independent of the finer details of the potential curve. By assuming a certain probable value, obtained from scattering experiments, for the width of the potential hole, it… Expand

The nature of the interaction between neutron and proton has assumed great importance in modern nuclear theory, since it is now generally assumed that these two particles form the fundamental… Expand

The static interaction of the Møller-Rosenfeld theory is used to calculate approximately the binding energies of the nuclei H2, H3, He3 and He4. The value of the meson mass and of the two other… Expand

In this paper we examine two situations apparently conflicting. On a side the Quantum Mechanics (QM) denies the presence of electrons within the atomic nucleus, so that it was shelved the doublet… Expand

Initially the neutron (N) was considered made by the very close union of a proton (P) and an electron (e), i.e. a doublet:〔P, e〕. This is the electron capture process, which involves also an… Expand

The large values of the singlet and triplet scattering lengths locate the two-nucleon system close to the unitary limit, the limit in which these two values diverge. As a consequence, the system… Expand

When one speaks of the three-body problem, the first characteristic that comes to mind is its “insolubility.” This describes the situation for the helium atom whose Schrodinger equation does not… Expand
