Molecular propagation through small avoided crossings of electron energy levels

This is the second of two papers on the propagation of molecular wave packe ts through avoided crossings of electronic energy levels in a limit where t he gap between the levels shrinks as the nuclear masses are increased. An e arlier paper deals with the simplest two types of generic, minimal multipli city avoided crossings, in which the levels essentially depend on only one of the nuclear configuration parameters. The present paper deals with propa gation through the remaining four types of generic, minimal multiplicity av oided crossings, in which the levels depend on more than one nuclear config uration parameter.
