Abstract
It is shown that the pseudopotential method can be used for an explicit calculation of the first few terms in an expansion in power of of the eigenvalues and the corresponding eigenfunctions of a system of Bose particles with hard-sphere interaction. The low-temperature properties of the system are discussed.
