High-spin states in <'161>Er have been studied experimentally using the <'150>Nd(<'16>O, 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 <'161>Er, 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.
