The cross section and frequency shift of the magnetic resonance line for the spin exchange are calculated for a collision of lithium and cesium atoms in the ground state. The calculation was carried out on the basis of data on the singlet (X1Sigma+) and triplet (a3Sigma+) interaction potentials of the 7Li133Cs dimer. The transfer from the energy to the temperature dependence of the real and imaginary parts of the complex cross sections for a spin exchange allows us to obtain information both the broadening of the magnetic resonance line of the atoms under study and the frequency shift of the magnetic resonance upon their collision.
