We present an extension of the model-potential method of Ne/sup *//sup *//(2p)/sup 5/(3p)/-Ne collisions. The role of the electronic inversion symmetry in the core--valence-electron separation for stationary nuclei is examined. This leads to approximate electronic eigenfunctions and corresponding adiabatic potentials. In this, an essential element is the R-dependent mixing of gerade and ungerade core potentials, associated with the R-dependent uncertainty of the valence electron being located at the Ne/sup +/ ion or the Ne atom. Subsequently, nuclear dynamics is included in the approximate wave function and the role of the identity of the nuclei is considered. With the aim of testing our extended approximate treatment, we also present experimental /sup 20/Ne/sup *//sup */-Ne, and /sup 22/Ne/sup *//sup */-Ne total polarized cross sections Q/sub l//sub left-arrow//sub k//sup chemically bond//sup M//sup >//sup k/chemically bond$ for the /(2p)/sup 5/(3p)//sub k/ (or //alpha///sub k/..-->..//alpha///sub l/) transition, with M/sub k/ the magnetic quantum number of the electronic angular momentum J of the initial //alpha///sub k/ state with respect to the asymptotic relative velocity.
