【 摘 要 】

This work is devoted to the calculation of complex cross sections for the spin exchange collisions between polarized alkali atoms. This is of interest for two reasons. First, knowledge of the cross sections allows one to quantitatively analyze spin-exchange collisions. Second, the obtained results can be used in practice to create quantum electronic devices with optical orientation based on the spin-exchange principle.
