摘要：

A high-resolution study of atomic manganese (Mn) covering the 3p &rarr nl resonance region with particular stress on the 3p &rarr 3d giant resonance was performed. The investigation was able to detect and characterize many of the 4s and 3d satellite lines and, particularly, the autoionizing-resonance states produced by 3p &rarr nl excitations with a reasonable degree of confidence by correlating photoelectron spectrometry and constant-ionic-state (CIS) spectra. The broad 3p &rarr 3d resonance around 50 eV was demonstrated to consist of a number of resonance states. The origin of the 'dip' in the partial cross section of the 3d(5D) main line. The first members of the 3p &rarr 5s, 6s, 4d, 5d series were identified and shown to mainly decay into excited Mn+ channels associated with satellite lines. Moreover, the behavior of the principal photoionization satellites were studied as a function of photon energy from 80 to 120 eV at much higher resolution than in previous experiments. Lastly, a limited study of the photon energy dependence of some very high-binding-energy satellites were also carried out.
