O. Plotzke et al., MAGNETIC DICHROISM IN THE ANGULAR-DISTRIBUTION OF ATOMIC OXYGEN 2P PHOTOELECTRONS, Physical review letters, 77(13), 1996, pp. 2642-2645
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.
