Configuration dependent pairing from band crossing frequencies
Abstract
Data are presented on the crossing frequencies of odd-parity rotational bands in 161Er. The crossing frequencies are shown to be correlated with the sign and magnitude of the quadrupole moments of the valence neutron orbits in odd-N rare earth nuclei. This can be understood in terms of configuration-dependent ``blocking'' of pairing-energy contributions requiring the inclusion of quadrupole terms in the pairing-correlation energy.
