Binary stopping theory for swift heavy ions
WebSwift heavy ions are the components of a type of particle beam with high enough energy that electronic stopping dominates over nuclear stopping. [1] [2] They are accelerated in particle accelerators to very high energies, typically in the MeV or GeV range and have sufficient energy and mass to penetrate solids on a straight line.

WebThis model was developed with the aim of calculating stopping forces for heavy ions at moderately high velocities, where a classical-orbital calculation is typically superior to the … 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 …
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 … WebStatistics of heavy-ion stopping Glazov, Lev G. ; Sigmund, Peter ; Schinner, Andreas Energy-loss straggling of swift heavy ions penetrating through matter has been analysed on the basis of binary stopping theory as well as the modified Bohr model allowing for projectile screening.
WebJun 1, 2004 · Stopping of light and heavy ions in compounds has been studied on the basis of the binary theory of electronic stopping with the focus on limitations of Bragg's … 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.
