摘要：

We have made simultaneous torsional oscillator and transverse cw NMR (at similar to 165 kHz) studies of the superfluid phase of He-3 in aerogel glasses of 1% and 2% of solid density. NMR occurs over a range of frequency extending from the Larmor frequency to higher values, but is strongly peaked at the Larmor value. This behavior, together with the magnetic-field independence of the effective superfluid density, provides convincing evidence for a B-phase state with an (n) over cap texture, in our spherical geometry, governed by the same energetic considerations as for bulk superfluid He-3-B.
