Continuum Electron Spectra Arising from a Dynamical Variation of the Molecular-Orbitals in Slow Kr+Xe Collisions

Abstract

The present experimental results indicate that the physical origin of the continuum electrons produced in 75--1050, keV Krⁿ⁺+Xe collisions (n=1-3) may be located in the KrXe quasimolecule. A direct radial- or rotational-type of coupling between the highly promoted MOs and the continuum states is suggested to be responsible for the observed nature of the exponential decay of the continuum electrons as a function of their energies. A simple empirical relation describing the cross sections of the electrons that are emitted due to a dynamical variation of the molecular-orbitals and have a broadened spectra beyond the classical cut-off frequency, is shown to yield a fair agreement with the observed data.
