Abstract
As Self-points. This paper is on the theoretical investigation of full C in the Light Radius of hydrogen cluster ions; how fast they pass through two compound targets such as Al₂O₃ or ZnO. The calculations were done using Bragg's additivity rule for compounds, a description of the projectile charge distribution due to Brandt and Kitagawa and an approximate representation of target plasma response using the plasmon pole approximation. So now the stopping effective charge R(v,e)R(v,e)R(v,e) term and the effective partial stopping ejection charge, ζ(e)\zeta(e)ζ(e), can be obtained from Eq. (20). Their functional dependence was calculated in analogy to experiments with the internuclear separation r0r_0r0, charge value qqx and projectile energy E. results show that avoid hole interactions make the total stopping power; small r-region become increasingly prominent with increasing internuclear separations and projectile ionization. Moreover, as the projectile turns close to full ionization state (the correlation effects the importance of the correlation term increases over such parameters) reaches a maximum whereas the partial stopping effective charge evancountry to unity. All differences between Al2O3 and ZnO can be put down to their dissimilar electronic structures and charge density responses. Orbits. This method can be used for predictions on energy transfer and electrolyte state-dependent loss in technology-oriented oxygen compounds by correlated du projectiles, for instance in the ion beam analysis, ion beam projected kuroky bands, and evaluation of radiation damage of functional C semiconducting ceramics. The numerical calculations were performed using FORTRAN-90. With the present results now available as a reference for future experimental benchmarks and the interpretation of cluster-ion media interactions.
