Evolution of the one-phonon mixed-symmetry 2(1,ms)(+) state in even-even Xe isotopes from inverse-kinematics Coulomb excitation

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