Zusammenfassung:	Recent measurements by Heinzmann, et al., of the spin polarization of photoelectrons ejected from xenon by unpolarized light are in serious disagreement with various theoretical calculations. In this letter we report an ab initio study of spin polarization using the relativistic random-phase approximation (RRPA). Excellent agreement is obtained between the present calculations and the experimental measurements by Heinzmann et al. for xenon, krypton, and argon.
