New Aspects of Nuclear Dynamics

Part of the book series: NATO ASI Series ((ASIB,volume 209))

Abstract

Due to the very strong interaction between nucleons at short distances, the nuclear shape giving the lowest energy for most light nuclei is spherical as it is the one that packs the nucleons as close together as possible. The stability of this spherical shape may be enhanced by quantum mechanics and the Pauli principle. The mean field acting quantum mechanically on a single nucleon allows only certain orbitals which may be filled with protons and neutrons according to the Pauli. rule. For a spherical mean field the orbitals are grouped in degenerate energy levels characterised by the total angular momentum j of the single nucleon. In this shell model of the nucleus energy gaps arise as each of the orbitals is filled. Hence nuclei near closed shells are especially stable and are spherical in their lowest states.
