【 摘 要 】

Synopsis A combined experimental and theoretical study on single capture in 30- and 100-keV He+on He collisions was per- formed. We report on experimental state-selective cross sections and projectile angular-differential cross sections and compared with the theoretical results by using dynamic screening classical trajectory Monte Carlo method (dCTMC), and the significance of different electron-electron correlations are discussed. The structure observed in the projectile angular-differential cross sections is explained in terms of Fraunhofer-type diffraction of the He+projectile de Broglie wave.
