Abstract
The lack of systematic band crossings at high spin in ,160Er and the selectivity of the single observed neutron band crossing at ħω>0.37 MeV in (i) indicate that static neutron-pair correlations are too weak for the excitation of a pair of quasineutrons, and (ii) can be explained in terms of the expected spectrum of single-neutron states in the absence of static pair correlations.
