Transverse NMR Measurements on SuperfluidHe3

Transverse NMR measurements on liquid ${}_{}{}^3{}_{}{}^{}\mathrm{He}$ are reported down to 0.7 mK at several pressures below 27 bar. In the $A$ liquid the quadratic NMR frequency shift is proportional to ${T_C}^2(1-\frac{T}{T_C})$. In the $B$ phase the integrated dynamic susceptibility falls to a limiting value which is 25% of the Fermi-liquid susceptibility. NMR data on the $A$ and $B$ liquids confined in the voids of fine powder are also presented.
