The influence of the s-wave scattering of background particles on the association or disassociation of molecules in a system composing of two species Fermi atoms with opposite spin and molecules is studied. This influence becomes evidence in the period of evolution when most of the particles in the system are molecules,where the scattering with repulsive potential is propitious to the formation of molecules. Sub-Poisson statistical distribution of the molecule field is observed.
