Consequences of neutron-proton pairing correlations for the rotational motion of the N=Z nucleus 72Kr

Description

High-spin states in the N=Z nucleus 72Kr were populated using the 40Ca(36Ar,2p2n) reaction at a beam energy of 145 MeV. The yrast band has been observed up to a tentative spin of 20ℎ. Nonyrast rotational structures have also been observed for the first time. The alignment of g9/2 protons and neutrons in the yrast band is observed to be significantly delayed relative to the heavier even-even Kr isotopes. Exact deformed cranked shell model calculations suggest that this could be due to the combined effect of isovector (T=1) and isoscalar (T=0) neutron-proton pairing correlations
