摘要： A study of single-electron capture (SEC) in 18-240 keV O$^{6+}$-Ne collisions has been conducted employing a combination of experimental and theoretical methodologies. Utilizing a reaction microscope, state-selective SEC cross sections and projectile scattering angle distributions were obtained. The translational energy spectra for SEC reveal the prevailing capture into $n=3$ states of the projectile ion, with a minor contribution from $n=4$ states. Notably, as the projectile's energy increases, the relative contribution of SEC $n=4$ states increases while that of SEC $n=3$ states diminishes. Furthermore, we computed state-selective relative cross sections and angular differential cross sections employing the classical molecular Coulomb over-the-barrier model (MCBM) and the multichannel Landau-Zener (MCLZ) model. A discernible discrepancy between the state-selective cross sections from the two theoretical models is apparent for the considered impact energies. However, regarding the angular differential cross sections, an overall agreement was attained between the current experimental results and the theoretical results from the MCLZ model.
