Description
Summary:The properties of the low-lying energy states for the super(100)Mo isotope is investigated within the framework of the proton-neutron interacting model IBM2. By considering the relative energy of the d proton boson to be different from that of the neutron boson and taking into account the dipole interacting among like-boson L sub([pi]) [middot] L sub([pi]) and L sub(v)[middot] L sub(v) the low-lying energy spectrum is reproduced well. Particularly, the relative position of the energies for (ProQuest: Formulae and/or non-USASCII text omitted) and (ProQuest: Formulae and/or non-USASCII text omitted) states shifted correctly fit the experimental data. The electromagnetic properties, including the key observable B(E2) reduced transition branching ratios and the E2 reduced matrix elements of the experimental data, are well described. Our calculations show possible shape coexistence in the super(100)Mo nucleus.
