Abstract [en]

Configuration-constrained nuclear shape calculations are used to show that reinforcing neutron and proton orbital structures create exceptional conditions for the formation of multiquasiparticle isomers in neutron-rich hafnium isotopes, with axially symmetric, prolate shapes. Highly excited, long-lived states are predicted. However, at angular momenta close to 40 (h) over bar, orbital alignment effects for collective oblate rotation lend to a deep potential minimum that competes energetically with the prolate multiquasiparticle states.
