Phys. Rev. A 69, 012708 (2004) [8 pages]State-selective electron-capture calculations for p-Ar collisions in an independent many-electron modelReceived 1 July 2003; published 21 January 2004 We extend previous calculations of many-electron processes in ion-atom collisions to the case of state-selective electron capture by protons from the K,L,M shells in argon at 1–200 keV/amu collision energies. The results are based on a time-dependent density functional theory framework and the basis generator method for the propagation of atomic orbitals. Impact-parameter-dependent probabilities are obtained from a statistical analysis. The results for capture to the H(K,L,M) shells are compared with experiments, and are found to agree with them much better than previous calculations. This serves as an indication that both a proper account of atomic structure and flexibility in the propagation of atomic orbitals are important. © 2004 The American Physical Society URL:
