Basis Generator Method Study of Collisions Between Alpha Particles and Lithium-like Ions

Abstract

Electron excitation, transfer and ionization in collisions between alpha particles and lithium-like ions are investigated by means of the Basis Generator Method (BGM), a specific coupled-channel approach to the time-dependent Schrödinger equation (TDSE). The gist of the BGM is the representation of the electronic wavefunction within a dynamically adapted finite model space including the physically accessible part of the electronic continuum. Theoretical results for total capture are in good agreement with recent experimental data.
