Nuclear moments of neutron-deficient iridium isotopes from laser spectroscopy

Abstract : Laser spectroscopy measurements have been performed on neutron-deficient iridium isotopes. The hyperfine structure and isotope shift of the optical Ir I transition 5d(7)6s(2) F-4(9/2) --> 5d(7)6s6p F-6(11/2) at 351.5 nm have been studied for the Ir182--189, Ir-186(m) and Ir-191,Ir-193 isotopes. The nuclear magnetic and quadrupole moments were obtained from the HFS measurements and the changes of the mean square charge radii from the IS measurements. A large mean square charge radius change between Ir-187 and Ir-186 and between Ir-186(m) and Ir-186(g) has been observed.
