Charge-transfer cross sections ofH+ions in collisions with Ne atoms in the energy range below4.0keV

Abstract

Total charge-transfer cross sections for ${\mathrm{H}}^{+}$ ions in collisions with Ne atoms have been measured in the energy range of $0.60\phantom{\rule{0.3em}{0ex}}\text{to}\phantom{\rule{0.3em}{0ex}}3.6\phantom{\rule{0.3em}{0ex}}\mathrm{keV}$ with the initial growth rate method and found to agree with the present rigorous calculation based on a molecular-orbital expansion method with the electronic states obtained by the multireference single- and double-excitation configuration interaction method. These observed cross sections are also compared with previously published data and theoretical prediction. It has been found that previous experimental data deviate significantly from the present observed and calculated cross sections as the collision energy decreases.
