Resource for calculations of optical pumping, following the methodology described in Eur. J. Phys. 38, 045703 (2017). The project contains explicit evolution matrices for different problems (that is, different configurations, atoms ), explicit equations for the time evolutions, mathematica codes, plotted results, and more. Itis done in a way that the project can gradually be expanded, with more and more atoms, more and more specific problems, and so on.We present results of a method for calculating optical pumping rates in 87 Rb, as described in [1]. We use light with an impure polarization (i.e. a mixture of σ + , σ − and π light) to populate a stretched angular momentum state in the F g = 2 hyperfine structure level of the ground state. The method is shown to function well for the studied system. Absolute scale level populations as functions of time, detuning, intensity, relative intensity of polarizations, and starting parameters are derived
