The direction of emission of photoelectrons from atoms is characterized by the angular distribtion parameter beta. Measurements of beta over an extended photon energy region can give insight into the dynamics of the photoionization process. Using synchrotron radiation from the Aladdin storage ring in Stoughton, Wisconsin, we have measured the beta values of the 3d photoelectrons from the open-shell chromium atom in the photon energy region from about 20 eV up to 160 eV. The angular distribution values show a steady increase from about 0.2 up to 1.2 at 80 eV where they remain essentially flat.
