NUCLEAR SPINS OF SIX NEUTRON-DEFICIENT GOLD ISOTOPES

The nuclear spins of six neutron-deficient isotopes of gold have been measured by atomic-beam magnetic-resonance methods. The results of these measurements are as follows: ${\mathrm{Au}}^{191}$ (3.0 hr), $I=\frac{3}{2}$; ${\mathrm{Au}}^{192}$ (4.8 hr), $I=1$; ${\mathrm{Au}}^{193}$ (17.5 hr), $I=\frac{3}{2}$; ${\mathrm{Au}}^{194}$ (39 hr), $I=1$; ${\mathrm{Au}}^{195}$ (190 day), $I=\frac{3}{2}$; ${\mathrm{Au}}^{196}$ (5.6 day), $I=2$.
