ABSTRACT
The goal of this paper is to obtain the unequal masses of the atoms moving in geometry of two component fermions system. The two component fermions systems have been considered. The fermion-dimer scattering length and dimer-dimer scattering length in the universal limit of large fermion-fermion scattering length have been computed. The scattering properties of the fermion-dimer, dimer-dimer and the mass ratio dependence of the universal fermion-dimer and universal dimer-dimer scattering length have been analyzed. Scattering properties of composed system indicate a deep understanding of the dynamics in many-body of an atom system.
