A Monte Carlo simulation of radiative transfer in an atomic helium beam is carried out to investigate the effects of radiation trapping on electron-atom collision experiments. By comparing the simulated and measured radiation intensity distributions the pressure at the collision site can be determined, while such information has been hitherto otherwise inaccessible.
