STUDY OF LIGHT NUCLEI WITH BRUECKNER-AMD+GCM

To describe excited nuclear states, we developed the Brueckner-AMD combining the Brueckner theory with Antisymmetrized Molecular Dynamics (AMD), which has been recently proposed as a new framework to study nuclear structure of light nuclei based on the realistic nuclear force. In the present framework, we formulate a multi-configuration calculation with Generator Coordinate Method (GCM) in the Brueckner-AMD. An application is shown for the excited states with positive and negative parities in 4 He , and the successful results and reliability of the present framework are discussed.

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.

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.
