Electronic Stopping Power of Amorphous Carbon for H2+ and H3+ Beams

Abstract

The electronic stopping power of amorphous carbon targets for H2+ and H2+ molecular beams has been analysed within the framework of the dielectric formalism. Coulomb explosion between the partners of the molecule has been taken into account to evaluate the average stopping power ratio during the dwell time. The charge state of the fragments is assumed fully stripped. Analysis and comparison of the calculated stopping power ratio with experimental data show a reasonable agreement.

“…Calculations based on the dielectric formalism yield an excellent agreement with experimental results and predicted a maximum stopping ratio of 1.5 for H + 2 molecules. 1 Other results concerning carbon [3][4][5][6] seem to be compatible with results presented in Ref. 1.…”
