Sarrazin WebWe report some highlights of our work with heavy-ion stopping in the energy range where Bethe stopping theory breaks down. Main tools are our binary stopping theory (PASS code), the reci-procity principle, and Paul’s data base. Comparisons are made between PASS and three al-ternative theoretical schemes (CasP, HISTOP and SLPA).

WebOct 1, 1998 · We present stopping power calculations for swift heavy ions in a hydrogen gas target. The point-like model is reviewed and compared to a new theory which includes the projectile elastic form factor. It is shown that, even for highly ionized ions, the projectile form factor yields a substantial modification over the standard stopping results. WebTo represent stopping for heavy ions at the highest energies co rrectly, it is necessary to use the non-perturbational LS theory which is fully relativistic and, in addition, assumes 1 While stopping power considers the energy reducing … high schools townsville
