O. Ingolfsson et al., Electronic shell model contemplation of the dissociation dynamics of Al-8(+): a collision-induced dissociation study, CHEM P LETT, 311(6), 1999, pp. 421-427
For the collision-induced dissociation of small cationic aluminum clusters,
the release of Al+ is known to dominate. An exception is Al-8(+), where we
find the neutral atom evaporation to be energetically favorable, and to co
uple strongly with the Al+ release. These experimental results are discusse
d in the frame of the Clemenger-Nilsson electronic shell model. We find the
electronic shell model to offer a consistent interpretation of the energy
dependence of the dissociation dynamics of Al-8(+), if the crucial role of
collisional deformation is taken into account. (C) 1999 Elsevier Science B.
