Identification of transitions in⁷³Kr and the search for large oblate deformation

Abstract

The gamma transitions in 73Kr have been identified for the first time by tagging the gamma rays with reaction products of mass 73 and neutrons produced in the reaction 40Ca (95 MeV 35Cl, pn) 73Kr. A gamma-gamma coincidence experiment was performed at Oak Ridge with a Compton suppressor array which utilises 20 Ge detectors equipped with Compton suppressors. Transitions in 73Kr have been placed into two bands. Several other transitions also are identified in 73Kr but not placed into the level scheme.
