Nuclear Spins of 165Lu, 168mLu and 172Lu

The nuclear spins of some neutron-deficient lutetium isotopes have been measured using the atomic-beam magnetic resonance method. The following results have been obtained: 165Lu (12 min) I = 1/2, 168mLu (6.7 min) I = 3 and 172Lu (6.7 d) I = 4. The spin values are discussed within the framework of the Nilsson model.
