Abstract

The lifetimes of several negative-parity states in126,130Xe and132Ba have been determined by means of the generalized centroid-shift method. The reactions124,128Te(α,2n) and122Sn(13C, 3n) have been used. Following results were obtained:T 1/2(2758 keV)=1.3±0.2 ns in126Xe,T 1/2(2060 keV)=0.20±0.10 ns,T 1/2(2104 keV)=0.50±0.10 ns,T 1/2(2376 keV)=0.30±0.10 ns andT 1/2(2973 keV)=4.6±0.4 ns in130Xe as well asT 1/2(2120 keV)=0.40 +0.20−0.10 ns in132Ba. A systematics of the B(E2; 7 1− ⇒5 −1 ) values in theN=76 nuclei is presented. Electric dipole and quadrupole transition rates are discussed in terms of octupole and quadrupole collectivity. The structure of the 5 −1 and 7 −1 states is considered.
