It is possible to obtain under pressure, in the absence of a free liquid-vapor surface, a metastable solution of liquid He/sup 3/ in liquid He/sup 4/ in the stratification region in the phase diagram. The rate of formation of nucleating centers in the volume of such a solution and its dependence on temperature and concentration are computed. Classical and quantum conditions for nucleation are analyzed. The cases of the normal and the superfluid states of the Fermi component in the solution are considered in the region of the quantum regime. It is shown that the stratification of the supersaturated solution under the indicated conditions should begin not on the phase-equilibrium line, but on the rapid-nucleation line, T/sub q/. The T/sub q/ line is constructed.
