Photoionization cross sections ({sigma}) and photoelectron angular distribution parameters ({beta}) across the ({ital ns}{prime},{ital nd}{prime}) autoionization resonances for Ar, Kr, and Xe have been measured with photon resolution widths as low as 0.023 A by means of synchrotron-based photoelectron spectroscopy. The experimental results are compared with those obtained by other experimental techniques and theoretical results. The enhanced resolution allows a redetermination of the width of the {ital ns}{prime} resonances.
