Abstract

The level structure of 80,82Sr was studied with in-beam γ-ray spectroscopy via the 78,80Kr(α, 2nγ)80,82Sr reactions at Eα = 28.7 MeV. From the angular distributions and γ-γ coincidence measurements, the ground-state band up to (10+) and some other states were observed in both nuclei. The deduced levels are compared with current theoretical models. The observed level structure in neutron deficient Sr isotopes indicates a transition from spherical to deformed as neutron number decreases from 50 to 40.
