Abstract
The contribution of the strong-coupling effects to the free energy of the "dirty" superfluid is estimated using a simple model. It is shown that the strong-coupling effects are less susceptible to the quasiparticle scattering events in comparison to the weak-coupling counterpart. This supports the conclusion about stabilization of the -phase in aerogel environment at pressures where the -phase takes over in bulk superfluid , in accordance with recent experimental observations in zero magnetic field.
