In the framework of collective variables method for binary mixture of non-ideal
Bose-gases (liquids) $s$-particle density matrices at $T=0$ are found. The ground state
energy, the excitation spectrum and correlation functions “density-density” are calculated
by means of variational method. The accordance between zero-order approximations
of the variational and microscopic approaches is demenstrated. Binary mixture of
Bose-gases of equal masses is taken as an example of a model of the “pseudopotential
of hard spheres”.
