Reorientation effect measurements in 124Te, 126Te and 128Te

Abstract

Coulomb excitation probabilities of the first 2 + states of 124Te, 126Te and 128Te have been determined. The measurement was performed by resolving the inelastically and elastically backward scattered 4He and 16O projectiles using an annular surface barrier detector. Quadrupole moments ( Q 2+) as well as the B(E2, 0 + → 2 +) values were extracted by analyzing the excitation probabilities with the Winther-de Boer multiple Coulomb excitation program. The Q 2 deduced for the positive sign of the 2 + interference term are −0.41 ± 0.08 e · b, −0.144 ± 0.11 e · b and −0.12 ± 0.09 e · b for 124Te, 126Te and 128Te, respectively.
