Description

The spectroscopic quadrupole moments of the neutron deficient radioactive Ir isotopes 184Ir, 186Irg, 186Irm, 187Ir, 188Ir, and 189Ir were measured with the technique of quadrupole-interaction-resolved NMR on oriented nuclei. The ratio of quadrupole moments of the 2- isomeric state 186Irm and the 5+ ground state186Irg points to different nuclear deformations in these states. In addition, we present a new method for the unambiguous measurement of ground state spins. copyright 1996 The American Physical Society
