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