Variation with mass of $\boldmath{B(E3; 0_1^+ \to 3_1^-)}$ transition rates in $A=124-134$ even-mass xenon nuclei

Abstract

$B(E3;0_1^{+}\to 3_1^{-})$ transition matrix elements have been measured for even-mass ${}^{124-134}$Xe nuclei using sub-barrier Coulomb excitation in inverse kinematics. The trends in energy $E(3^{-})$ and $B(E3;0_1^{+}\to 3_1^{-})$ excitation strengths are well reproduced using phenomenological models based on a strong coupling picture with a soft quadrupole mode and an increasing occupation of the intruder $h_{11/2}$ orbital.
