The angular asymmetry parameter ..beta.. for the Xe 5s..-->..epsilonp photoelectrons has been studied with use of synchrotron radiation (h..nu.. = 28--65 eV). The present results show that the relativistic random-phase approximation theory does not satisfactorily describe the Xe 5s photoionization process close to the Cooper minimum and thus require a renewed theoretical approach. The 5s partial photoionization cross section was obtained over the same photon region and the results agree with experimental values found in the literature.
