摘要: The ionization bands and electron affinities of medium-size BnNn clusters (n = 3, 4, 5) have been investigated by means one-particle Green's function calculations using the outer-valence (OVGF) approximation or third-order algebraic diagrammatic construction [ADC(3)] scheme. Despite their structural similarity with isoelectronic cumulenic carbon chains rings, these do not exhibit a significant breakdown orbital picture ionization, exception N2s (eb > 25 eV), which relate exclusively to complex sets shake-up lines. main (one-hole) provide specific signatures for ring topologies based on n equivalent vertices, whereas reduction curvature N−B−N bridges increasing system size can be followed from bands. B3N3- anion is slightly stable against loss, negative vertical are obtained B4N4 B5N5.
