Abstract
Experiments were performed to measure the absolute total electron-capture cross sections for collisions of Ne3+ ions with hydrogen atoms at energies between 0.07 and 826 eV/u. An enhancement in the magnitude of both the experimental and theoretical cross sections was observed which is attributed to an ion-induced dipole attraction between the reactants. The present experiment showed a significant target isotope effect below ∼4 eV/u. Modern quantum chemistry calculations were recommended to improve the molecular-orbital close-coupling (MOCC) calculations.
