A Shell Model Study of the Proton-Neutron Interacting Boson Model

Part of the Ettore Majorana International Science Series book series (EMISS, volume 10)


The proton — neutron interacting boson model (P-N IBM; also called IBM-2) has been recently proposed to describe quadrupole collective states in medium-heavy nuclei.1,2 The P-N IBM consists of proton bosons of L=0 (called sπ) and L=2 (called dπ), and neutron bosons of L=0 (called s v ) and L=2 (called d v ). A two-body interaction between them is assumed. In terms of this model, numerous phenomenological analyses of the collective states have been performed over a wide range of the periodic table.3

    The shell model space is truncated in most of diagonalizations because of the limitation of the computing facility. The dimension of the shell model space is, however, still much larger (ti 3000 dim.) than that of the S-D subspace 60 dim.), and this truncation causes practically no effects on final conclusions. Discussions in this talk do not have to be in 0.1% precision.Google Scholar
