Abstract

The nuclear spin and hfs splitting of $O^{15} (τ_{\frac{1}{2}} = 124 sec)$ in the ${}^{3}P_{2}$ atomic ground state have been determined by the atomic beam magnetic resonance method. $O^{15}$ was produced in the reaction $N^{14} (d, n) O^{15}$ by allowing a 5-MeV deuteron beam from the Columbia Van de Graaff accelerator to impinge upon a gaseous $N_{2}$ 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 $O^{15}$ in the ${}^{3}P_{2}$ state is observed to be 1037.23±0.07 Mc/sec, and the nuclear magnetic dipole moment of $O^{15}$ is deduced to be 0.7189±0.0008 nm.
