Problem of strong interaction of the nonrelativistic particle with scalar quantum: field is considered with the aid of N.  N. Bogoliubov's transformation. Relation between the particle mass and the effective mass of the field can be arbitrary. The equations which determine the stationary state of the system are found in the first approximation.
