Signature of the shape coexistence in 72Kr: discontinuities of the moment of inertia at low spin
The low-lying level structure of the N=Z nucleus 72Kr was studied by 40Ca(35Cl, p, 2nγ)72Kr at 95 MeV. Gamma ray coincidences are used to construct for the first time a level scheme for this nucleus based on coincidence gating with the previously identified 2+-0+ transition. The new level scheme indicates strong prolate-oblate mixing of two shape coexisting bands. The results support theoretical predictions of a stable oblate minimum in this region. © 1990.
