Rotational Spectra of the Ground-State Bands of Even Nuclei by the Generator-Coordinate Method

The low-lying level structure of 31 Mg has been investigated by the theoretical framework of deformed-basis antisymmetrized molecular dynamics (DAMD) plus generator coordinate method (GCM) with the Gogny D1S force. It is shown that the N =20 magic number is broken and the intruder configuration (neutron 2p3h configuration) dominates the ground state. The observed data such as the magnetic moment and β decay strength are well reproduced.

Multichannel Analysis

This work is devoted to a Generator-Coordinate-Method investigation of the 16 B spectrum with an Extended Two-Cluster Model which includes many 15 B + n channels. We find that the narrow peak above the 15 B + n threshold seen in the experiments of Kalpachieva et al. and of Lecouey et al. can be assigned to a [Formula: see text] resonance. Several resonances are obtained near the 15 B + n threshold, in particular a [Formula: see text] state which could be a possible candidate for the 16 B ground state. Comparison with Shell Model calculations is performed.

AbstractIt is shown that the cluster expansion formalism previously developed as a basis for a theory of the ground state of correlated systems may be generalised in such a way as to enable the application of the generator coordinate method in the presence of singular interactions, thereby providing also a theory for excited states.
