High-spin Spectroscopy Near the Deformed N~Z~38 Shell Gap: The Light Rb Isotopes
(1997) In Progress in Particle and Nuclear Physics 38. p.101-110- Abstract
- Nuclei near the prolate single-particle energy gap at proton number Z = 38 (epsilon(2) approximate to +0.38) and neutron number N approximate to Z offer unique possibilities to study the pn-interaction at large quadrupole deformation, In the yrast band of the Z = N = 37 nucleus Rb-74, We have identified a crossing of the T = 1 pn-paired band (even spins) with the T = 0 pn-unpaired band (odd spins). In Rb-77, the positive-parity yrast and yrare bands have been followed over large spin ranges and assigned different 1qp-proton 2qp-neutron structures. These band crossings do not follow the usual pattern of two identical particles aligning in high-j orbits, In addition, an aligned g(9/2) proton-neutron negative-parity sequence with K = 11/2 has...
