Abstract
The nuclear spin and hfs splitting of in the atomic ground state have been determined by the atomic beam magnetic resonance method. was produced in the reaction by allowing a 5-MeV deuteron beam from the Columbia Van de Graaff accelerator to impinge upon a gaseous target. The radioactive gas flowed continuously from the target chamber into the microwave discharge source of the atomic beam apparatus. A rotating-wheel deposition detector specially suited for shoft-lived radioactive atoms was used to detect the beam. The spin is found to be ½, in agreement with the shell-model prediction. The hfs splitting of in the state is observed to be 1037.23±0.07 Mc/sec, and the nuclear magnetic dipole moment of is deduced to be 0.7189±0.0008 nm.
