WebAbstract. In the slowing-down of heavy ions in materials, the standard description by Lindhard and Scharff assumes the electronic stopping cross section to be proportional to the projectile speed v up to close to a stopping maximum, which is related to the Thomas-Fermi speed v TF.It is well known that strict proportionality with v is rarely observed, but … WebJun 1, 2004 · Binary stopping theory needs the following numerical input: • Resonance frequencies and oscillator strengths, • orbital velocity spectra and • binding energies for all shells and/or subshells of the target and the projectile. Finding suitable data for resonance frequencies and oscillator strengths has been described in [15], [22]. fishing equipment rental marathon fl
