Reinvestigation of the high spin states in ^（161）Er and enhanced E1 transitions in the N=93 isotones

Reinvestigation of the high spin states in ^（161）Er and enhanced E1 transitions in the N=93 isotones

High-spin states in 161Er have been studied experimentally using the 150Nd（16O, 5n） reaction at a beam energy of 86 MeV. The relatively enhanced E1 transitions between the 5/2＋[642] and 3/2-[521] bands are observed in 161Er, and the B（E1） values are extracted experimentally. The systematics of the R...

description High-spin states in 161Er have been studied experimentally using the 150Nd（16O, 5n） reaction at a beam energy of 86 MeV. The relatively enhanced E1 transitions between the 5/2＋[642] and 3/2-[521] bands are observed in 161Er, and the B（E1） values are extracted experimentally. The systematics of the R（E1） values in the N = 93 isotones are presented. It is found that the strength of the E1 transitions obviously exhibits angular momentum dependence, and the occurrence of the relatively enhanced E1 transitions could be attributed to octupole softness.
