Evolution of the one‐phonon mixed‐symmetry 21,ms+state in even‐even Xe isotopes from inverse‐kinematics Coulomb excitation

Coulomb excitation experiments in inverse kinematics on beams of stable {sup 134,132,130,128,126,124}Xe ions impinging on a carbon target at energies of 82% of the respective Coulomb barriers have been performed. The one-phonon 2{sub 1,ms}{sup +} states have been tracked and identified in {sup 134,132,130,128}Xe from the 2{sub i,ms}{sup +}{yields}2{sub 1}{sup +} M1 strength distributions and from 0{sub 1}{sup +}{yields}2{sub i,ms}{sup +} E2 strength distributions responsible for the one-step Coulomb excitation processes. The evolution of the one-phonon 2{sub 1,ms}{sup +} state within the seven even-even stable Xe isotopes is here presented.
