Inversion of He-Ne elastic scattering data

Creators

Description

Quantal and semi-classical (WKB) methods of inversion have been used in an analysis of the elastic scattering cross sections for 62.5 MeV helium atoms from neon atoms by which an effective local interaction between those atoms is specified. The potentials obtained by the approximate method (WKB) differ from that found with the full quantal analysis. The quantal inversion potential is repulsive at short distances and becomes attractive at a radius of 2.695 Angstroms. It has a minimum value of -1.981 MeV at a radius of 2.98 Angstroms. 15 refs., 3 tabs., 3 figs
