The generalized geometrical model utilized for the interpretation of photoelectron spectra is extended to the photoionization from polarized atoms. Within this model, the linear magnetic and the linear alignment dichroisms in the photoemission are calculated. The theoretical results are compared to those obtained from high-resolution angle-resolved photoelectron spectra, which were recorded upon 2p−1 photoionization of sodium atoms oriented in the Na 2p63s 2S1/2 ground and Na* 2p63p 2P1/2 laser-excited states or aligned in the Na* 2p63p 2P3/2 state. Good overall agreement is found between theory and experiment.
