Abstract
High spin states in 161Er and 162Er have been populated using the 130Te+36S reaction at a 36S bombarding energy of 170 MeV. In 161Er, three rotational bands were extended from I approximately=35 h(cross) to I approximately=50 h(cross). In 162Er the lowest energy positive parity band was observed to I=44 h(cross) and two negative parity bands to I approximately=32 h(cross). The behaviour of these rotational sequences are explained in terms of the expected spectrum of single neutron states in the absence of static neutron pair correlations.Keywords
