The article studies interactions involving spin-polarized alkali metal atoms in the ground state. The calculation of spin exchange and elastic scattering cross sections for the Na-Rb pair is performed. The calculation of the cross sections is carried out for the range of atomic collision energies from 10-4 to 10-2 a. u energy. The presented calculation allows for the first time to obtain the temperature dependences of the cross sections under consideration, which in turn can be used to consider the kinetics of polarization transfer during optical neutron scattering of atoms. Keywords: collisions of polarized atoms, indirect polarization, cross sections.
