Resumen
We use the classical trajectory Monte Carlo method to analyze charge exchange processes between fully stripped projectiles with H(1s) in a screened environment at impact energies in the range 18 eV/amu to 10 keV/amu. For Fe26+ projectiles, (n,l)-state selective charge exchange and line emission cross sections are presented for Debye screening lengths from 15 a.u. up to the unscreened case limit. At low-impact energies, a strong dependence of the hardness ratio on the Debye screening length is found. We show that such strong dependence also evidences itself for Ne10+,P15+,Ar18+, and Kr36+ projectiles. Clear indications of this dependence are noticeable in the photonic spectra even for large screening lengths (∼100 a.u.).
