Title

EVOLUTION OF SHAPES IN EVEN-EVEN NUCLEI USING THE STANDARD INTERACTING BOSON MODEL

Pages

  127-133

Abstract

 The sd-version of the INTERACTING BOSON MODEL (IBM) is used to establish the shape phase transitional structure. A simplified Hamiltonian is used which is intermediate between the three dynamical symmetries of U (6), namely the spherical U (5), the prolate and oblate deformed SU (3) and the g-unstable O (6) limits. The POTENTIAL ENERGY SURFACEs (PESs) to the IBM Hamiltonian have been obtained using the intrinsic state formalism which introduces the shape variables b and g. The Gadolinium (Gd) and Ruthenium (Ru) isotopic chains have been taken as examples in illustrating the U (5)-SU (3) and U (5) - O (6) shape phase transitions, respectively. We used the standard c2 test to get the IBM Hamiltonian parameters. The fit is performed by minimizing the c2 function for some selected experimental low-lying energy levels, the two neutron separation energies and B (E2) transition rates.
