A Lagrangian density, inspired by the Ginzburg-Landau model of the superconductivity, has been constructed with the purpose of highlightening the role played by the boson fields characterizing the Padua model of the nucleon.

A chromomagneto-electric Lagrangian density has been constructed with the purpose of investigating the confinement property of the chromo-electric potentialV\(q\bar q\)(γ). It is shown that the confinement arises both from a term inV\(q\bar q\)2(γ)

The essential aspects of a new model of the nucleon are developed, and a nucleon-nucleon potential is therefrom deduced in the framework of the meson exchange theory. The preliminary results are promising and the model discloses interesting theoretic

Nucleon eigenvalues in finite nuclei are evaluated by means of a variation-iteration method applied to the homogeneous Fredholm’s equation in momentum space. The shell model potential deduced in preceding papers is used; its remarkable feature is t

It is shown that the radial dependence of the central and spin-orbit parts of the shell model potential, evaluated numerically in a preceding paper, can be described with a high degree of accuracy by a simple, but unconventional, explicit function, w

The aim of this paper is to outline a mathematical scheme for the description of the overall behaviour of infinite nuclear matter: it has been conceived with the pragmatic purpose of providing simple tools for carrying out realistic numerical calcula

The theory of atomic hyperfine structures is re-formulated and the possibility of extracting information on the skin thickness of nuclear-charge distributions from the analysis of such structures is pointed out.
