Title: Proton excitation of fine-structure transitions in Fe XIV

Abstract

The interaction potentials of the quasimolecular ..sigma.. and Pi states formed by the approach of a proton and the positive ion Fe/sup 13 +/ are calculated in an approximation which reproduces the long-range quadrupole and polarization terms and which accounts properly for short-range penetration effects. The interaction potentials are used in quantal calculations of the cross sections for proton-impact excitation of fine-structure transitions of Fe/sup 13 +/. Solutions of the close-coupled scattering equations are obtained and the resulting cross sections are compared with those given by the Coulomb-Born and elastic approximations. The sensitivity of the cross sections to features of the interaction potentials is explored. The Coulomb-Born and elastic approximations do not always reflect faithfully the physical characteristics of the potentials.
