AbstractThe g factors of 21+, 41+, and 22+ states in the stable 130,132,134,136Xe 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(21+) as the number of neutron holes increases in the lighter nuclei below the closed N = 82 neutron shell. The g factors of the 41+ states in 132,134Xe are consistently larger than the g factors of the 21+ states, a characteristic of proton excitation. The g factors of the 21+, 41+, and 22+ states in 130Xe are approximately equal as would be expected for vibrational excitations.
