The Bloch correction, key to heavy-ion stopping

WebBinary theory of electronic stopping, developed recently with the aim of quantifying stopping forces on swift heavy ions, has been applied to antiproton stopping. Essential ingredients in the theory are inverse-Bloch and shell corrections. The numerical input consists of the excitation spectrum of the stopping material, characterized by bundled … WebSep 1, 2012 · The largest part of the energy loss of swift heavy ions (SHI) with energies higher than 1 MeV/amu and masses more than 20 proton mass is realized due to excitations of the electronic subsystem of a target. The electronic stopping Se (3–10 keV/nm) constitutes more than 95% of the energy loss of such an ion. WebBinary stopping theory, although developed to describe heavy-ion stopping, has a potential in light-ion stopping which is examined in this paper. We study antiprotons, hydrogen and helium ions penetrating through elemental materials and lithium fluoride. billy idol bitter sweet

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 … 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).

WebBinary stopping theory has been developed to characterize the electronic stopping of swift heavy ions in matter. It is an extension of Bohr's classical theory of 1913 incorporating screening, higher-order- Z1and shell corrections, high-speed quantum and relativity corrections as well as projectile excitation and ionization. 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].
