【 摘 要 】

State-resolved charge exchange (CX) cross sections for Be4+, C6+, N7+and O8+projectiles colliding with atomic hydrogen are evaluated employing two different methods: the Classical Trajectory Monte Carlo (CTMC) and the eikonal impulse (EI) approximations. These cross sections are used to extend previously derived scaling laws for n-, nl-, and nlm- distributions to highly excited final levels with 4 ≤ n ≤ 9, covering energies in the range 50-2000 keV/amu. Present results are in agreement with available experimental and theoretical data for these collision systems, becoming a useful instrument for plasma research.
