Formation of potassium cyanide clusters in the direct laser vaporization of K 3 [Fe(CN) 6 ] was studied by use of a TOF mass spectrometer. It was found that the positive cluster ions are due to [K(KCN) n ] + , n = 0-37, in which magic numbers are n = 4, 13, 22, 37, whereas the negative cluster ions were assigned to [(KCN) n CN] - , n = 0-13, where magic...
Calculations with extended basis sets and full intrachannel coupling of discrete and continuum states suggest an alternative interpretation of the NEXAFS spectrum of molecular oxygen. In this interpretation the roles of valence-Rydberg mixing and intrachannel discrete-continuum interaction are stressed at the expense of the exchange splitting mechanism. Calculations indicate that only the doublet-parent...
