Abstract

A novel implantation-decay technique has been employed to measure the magnetic moments of the 2(1)(+) states in the neutron-deficient nuclei Pt-184, Pt-186, and Pt-188. The magnetic moment systematics for the even Pt isotopes now extend from Pt-184(78)106 to Pt-198(78)120, spanning the upper half of the valence neutron shell. Despite the prolate-to-oblate shape transition near A = 190, they remain remarkably constant. The g(2(1)(+)) values for Pt-184, Pt-186, Pt-188 are consistent with shape-coexistence models in which the deformed configuration has a larger effective number of valence protons than the less-deformed configuration.
