✦ Synopsis

The free energy of the Fermi-gas with repulsive interaction is calculated below the critical temperature T c, which corresponds to the first instability of the normal state. It is shown that in both cases T--~ Tc and T = 0 this instability really leads to lowering of the free energy, i.e. the triplet superconductive B-phase states takes place for all temperatures T < T c.
