Abstract

Rotational bands based on two-quasi-neutron excitations have been observed for the first time in neutron-rich isotopes. The bandhead excitation energies have been used within the BCS model to determine the strength G of the neutron pairing interaction. Values of G=0.21 and 0.19 MeV have been obtained for Zr100 and Zr102, respectively. For these neutron-rich nuclei the strength G is thus close to 20/A MeV, smaller than the value 23/A MeV used to describe even-even nuclei near stability in this region. © 1995 The American Physical Society.
