摘要: The photoionization of argon clusters with an average size 270 atoms per cluster was investigated in the vicinity Ar 3s → np autoionizing resonances using angle-resolved time-of-flight photoelectron spectroscopy. 3p outer-valence spectra were measured as two-dimensional maps that show resonance profiles for free well cluster. For first time, partial yields and angular distributions two spin–orbit components are reported a function photon energy. photoelectrons differ substantially from atomic ones and, moreover, allow identification bulk surface resonances.
