We perform shell model calculations using a quadrupole–quadrupole interaction (Q.Q). We show results in single j shell spaces and the full S-D shell. We show that one gets useful results with Q.Q in both spaces. We emphasize the importance of the choice of single particle energies in order to obtain the results of Elliott using a Q.Q interaction without the momentum terms. We show a [Formula: see text] spectrum for a ground state band but with [Formula: see text]’s different from the rotational…

A method is derived for calculating matrix elements of a two-body interaction in wave functions which were classified in part I interms of the group U2-. For simplicity, a Cartesian basis of

The Nuclear SU3 Model

The shell model, despite a somewhat checkered career, has emerged as a useful approximation to the many-particle description of the atomic nucleus (E57b, S63). In principle it is perhaps the closest

Seniority conservation and seniority violation in the g9/2 shell

The g{sub 9/2} shell of identical particles is the first one for which one can have seniority-mixing effects. We consider three interactions: A delta interaction that conserves seniority, a

To understand how collective motion can develop in the shell-model framework it is necessary to study configuration interaction. With this in mind, group-theoretical methods are used to investigate

Microscopic theory of the nuclear collective model

This articles reviews the development of a microscopic theory of nuclear collective structure as a submodel of the nuclear-shell model. It starts by showing how the so-called geometrical
