Abstract

The classical-trajectory Monte Carlo method is used to calculate total and final nf state-selective electron capture cross sections for various fully stripped ions, ranging from He²⁺ to Ne¹⁰⁺, incident on H(ni = 1-4) and Li(2_s and 2_p) targets over the collision energies of 1-100 keV u^-1. Theoretical derivations of two scaling laws for state-selective electron capture cross sections as a function of collision energy, initial and final bound electron states and projectile charge are presented. The new scaling rules reduce the state-selective capture cross sections to very distinct universal curves. Curve fits to the state-selective cross sections are presented to provide additional information about the peak locations and magnitudes as well as the behaviour of the reduced cross sections as a function of collision energy. The scaling laws developed in this report allow for the prediction of state-selective electron capture cross sections in low-energy regions where experimental data have been limited or non-existent.
