Evidence for proton excitations in Xe-130,Xe-132,Xe-134,Xe-136 isotopes from measurements of g factors of 2(1)(+) and 4(1)(+) states (Journal article)

The g factors of 2(1)(+), 4(1)(+), and 2(2)(+) states in the stable Xe-130,Xe-132,Xe-134.136 isotopes have been measured via projectile Coulomb excitation in inverse kinematics in combination with the transient field technique. The results show a steady decrease in g(2(1)(+)) as the number of neutron holes increases in the lighter nuclei below the closed N = 82 neutron shell. The g factors of the 4(1)(+) states in Xe-132,Xe-134 are consistently larger than the g factors of the 2(1)(+) states, a characteristic of proton excitation. The g factors of the 2(1)(+), 4(1)(+), and 2(2)(+) states in Xe-130 are approximately equal as would be expected for vibrational excitations.
