A problem of the interatomic potential calculation for the boson system is considered. Expressions relating the Fourier-image of the interatomic potential and the structure factor are utilized to obtain a non-linear integral equation in the low- density limit. The model of 'almost hard spheres' is used as the initial approximation. This model in the limiting case turns into the hard spheres but it has no non-analiticities which cause difficulties in the numerical computations.
