The low-energy scattering of electrons from alkali atoms is of considerable theoretical interest because of the relative simplicity of the scattering problem. Spin-exchange optical pumping experiments provide a convenient means for studying electron-alkali atom collisions at thermal energies. In such experiments, free electrons are polarized in a weak magnetic field by spin-exchange collisions with optically-pumped alkali atoms. If an rf field is applied at the electron spin resonance frequency, the electrons are depolarized and spin-exchange collisions partially depolarize the alkali atoms. The depolarization of the alkali atoms results in a decrease in the intensity of the pumping light transmitted by the optical-pumping cell. In this way, one can observe the free electron spin resonance.
