Transitional nature of strontium isotopes

In the present report, the calculation of potential energy surface (PES) for the Sr isotopes have been reported. It is an extension of the previous work. The earlier work showed a clear indication of varying structure for Sr isotopes from a deformed rotor to a spherical vibrator. It is further studied using the PES diagrams. In this paper two description have been followed and studied the geometrical interpretation of IBM-2 and plotted PES as a function of β and γ parameters. In Sr nuclei the proton bosons are particle like and neutron bosons are hole like and therefore the neutrons and protons are likely to have opposite intrinsic quadrupole deformation
