Abstract : The matrix elements needed for optical pumping calculations in atomic H are tabulated. Stochastic relaxation matrices assuming randomization of electron spin are given. Stochastic pumping matrices neglecting interference terms are presented. Curves giving the equilibrium ground state populations as a function of the ratio of optical pumping time constant to relaxation time constant were obtained by digital computation using these matrices. Interference terms are important in atomic H since the excited hyperfine splittings are small. An evaluation of these terms for the case of sigmapumping is presented. An approximate numerical calculation for this case shows that the equilibrium populations are changed only by 510%, so the curves given are useful as rough experimental guides. (Author)
