Abstract : The purpose of the report is to present calculations of the relative populations of the ground state Zeeman sublevels of an optically pumped alkali atom. Two modes of optical pumping--zero mixing and complete mixing in the excited state--and three modes of alkali relaxation--uniform, Zeeman, and electron randomization--are considered. Calculations of the sublevel relative populations for an alkali atom of nuclear spin 3/2 are then made in terms of experimentally measurable parameters for all six combinations of pumping and relaxation modes. The numerical results are summarized in tables as functions of pumping and relaxation rates. (Author)
