Description

Abstract A program is presented to calculate various experimental observables as bilinear products of scattering amplitudes for impact excitation of (quasi) one-electron atoms by a spin polarized electron beam. Furthermore, it is demonstrated how experimental data for a minimum set of observables can be “inverted” to extract the scattering amplitudes. A successful and unique inversion of such data corresponds to a “complete experiment”. Title of program: ALKALI-OBSERVABLES Catalogue Id: ACVN_v1_0 Nature of problem This program calculates a large number of observables that have been defined in the literature for both unpolarized and spin polarized electron impact of atomic hydrogen or quasi one-electrons atoms and ions [1,2]. Given partially complete experimental data for some of these observables, the code can be used to "invert" these data and obtain the scattering amplitudes - up to some ambiguities which can, however, be resolved with some confidence by comparing with accurate theoretical results. Versions of this program held in the CPC repository in Mendeley Data ACVN_v1_0; ALKALI-OBSERVABLES; 10.1016/0010-4655(94)90219-4 This program has been imported from the CPC Program Library held at Queen's University Belfast (1969-2019)
