Abstract:
Stimulated by the results of NMR experiments with superfluid
3He in “nematically ordered” aerogel

we report on the
results of phenomenological analysis of stability of different phases of
superfluid 3He subjected to a strong homogeneous uniaxial anisotropy. On
a basis of this analysis we suggest a form of the order parameter for the new
ESP2 phase observed in the quoted experiments. In the weak coupling limit the
suggested order parameter approaches that of the axi-planar phase. We discuss
a possible experimental check of the proposed identification of the new
phase.
