Conventional theory and computation of the slowing-down of ions and associated radiation effects relies on a scheme proposed by Lindhard and Scharff, in which electronic energy losses enter as a friction force. We study limitations of this scheme, wh

We have explored the systematics of the magnitude and location of the Bragg peak in the stopping of ions in matter in terms of the atomic numbers Z 1 and Z 2 of the projectile and target species, respectively. Extensive analysis of experimental resul

We have studied systematic deviations of reported electronic stopping cross sections from velocity proportionality predicted by Lindhard and Scharff. Most pronounced is an apparent drop-off at beam energies below ∼ 0.01 MeV/u. In the frequently-use

Systematics of heavy-ion charge-exchange straggling

Autor: Andreas Schinner, Peter Sigmund

Publikováno v: Sigmund, P & Schinner, A 2016, ' Systematics of Heavy-Ion Charge-Exchange Straggling ', Nuclear Instruments & Methods in Physics Research. Section B: Beam Interactions with Materials and Atoms, vol. 384, pp. 30-36 . https://doi.org/10.1016/j.nimb.2016.07.016

The dependence of heavy-ion charge-exchange straggling on the beam energy has been studied theoretically for several ion-target combinations. Our previous work addressed ions up to krypton, while the present study focuses on heavier ions, especially
