Scaling for state-selective charge exchange due to collisions of multicharged ions with hydrogen

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 pre...

Descripción
Sumario: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. © Published under licence by IOP Publishing Ltd.
