摘要: Mass spectra of metal‐rich, singly and doubly ionized BanOx clusters are characterized by high peak intensities for n=13, 19, 23, 26, 29, 32, 35 independent the number oxygen atoms (x=1,2,3,4). These values identical to magic numbers found Ar clusters. The mass CanO show a similar behavior. stoichiometric, [Ca(CaO)n]++ low n=14, 24, 38, 40, 50, 64. correspond unstable formed addition one Ca atom or CaO molecule closed rectangular block with rock salt structure.
