Abstract
A substantial difference in the angular distributions of 2p photoelect rons from polarized oxygen atoms was found for two antiparallel atomic polarizations. This magnetic dichroism was studied as a function of p hoton energy from 25 to 52 eV. Our method extends traditional photoele ctron angular distribution measurements of open shell atoms to ''compl ete'' experiments in similar to spin-resolved measurements. The observ ed dichroism allows a determination of the dipole matrix elements for the epsilon s and epsilon d photoelectrons and their phase difference including the sign.
