Nuclear Spins Of Au-186, Au-187, Au-188, Au-189, Au-189m

The nuclear spins of some neutron deficient gold isotopes have been measured using the atomic-beam magnetic resonance method. The following results have been obtained: 186 Au 10.7 min) I = 3, 187 Au (8.5 min ) I = 1 2 , 188 Au (8.8 min ) I = 1 2 , 189 Au (28.3 min ) I = 1 2 and 189 m Au (4.6 min ) I = 11 2 . The spins of these typical transitional nuclei are discussed briefly in terms of various nuclear models.
