摘要：

We report the first measurements of the longitudinal resonance frequency [nu(long)(A)] in He-3-A in the low-temperature limit, as well as new measurements near T(c). In the low-temperature limit, our data agree well with theoretically predicted behavior. The data allow us to make the first estimates of the BCS cutoff energy as a function of pressure and of the zero-temperature A-phase energy gap.
