NUCLEAR PARAMAGNETIC SUSCEPTIBILITY OF THE POSSIBLE LOW-TEMPERATURE PHASE OF LIQUID He$sup 3$
S>Because a model of Brueckner, Soda, Anderson, and Morel based on the BCS model predicts that liquid He/sup 3/ will undergo a second-order phase transition to a highly correlated phase at approximately 0.06 deg K, the behavior of liquid He/sup 3/ in the presence of a magnetic field is calculated on the basis of the model, using the method of Bogoliubov et al. A critical magnetic field is found above which the low-temperature phase cannot exist, but the critical field is so high ( approximately 10/sup 6/ gauss) that the result reduces to Yosida's result in the spherically symmetric case. A plot of the magnetic susceptibility vs. temperature for the case 1 = 2, m = 2 shows that an attraction in He/sup 3/ in relative d states predicts a rather sharp drop in the susceptibility at the critical temperature. Since no such sharp change was observed down to 0.035 deg K, it is concluded that there is no evidence for a highly correlated low-temperature phase of He/sup 3/ above 0.035 deg K. (D.L.C.)
