Abstract

Excited states of the N = Z nuclei ⁷²Kr, ⁷⁶Sr and ⁸⁰Zr have been studied in a series of experiments involving Gammasphere plus Microball, and Gammasphere plus the Argonne Fragment Mass Analyzer. The ground state band of ⁷²Kr has been extended to a spin of (26⁺), and a very pronounced delay in the alignment of g_9/2 particles is evident. The ground state bands of ⁷⁶Sr and ⁸⁰Zr have been observed to spins 14⁺ and 12⁺, respectively, and also show evidence for delayed alignments. This delay in alignment may be a signature for neutron-proton pairing correlations.
