Abstract

It was found that two different spin states of the A-like phase can be obtained in an aerogel sample. In one of these states, we have observed the signal of the longitudinal NMR, while, in the other state, no trace of such a signal was found. The states also have different properties in transverse NMR experiments. A longitudinal NMR signal was also observed in the B-like phase of He-3 in aerogel.
