Skewness of energy-loss straggling and multiple-scattering energy distributions
Energy spread distributions due to electronic energy-loss straggling and multiple small-angle scattering of swift ions in matter are approximated by asymmetric Gaussian functions consisting of two-piece normal distributions. These skewed energy distributions approximate the distributions more accurately than the conventional approximation by Gaussian functions. The results are compared to exper...
متن کاملoptimal control of light propagation by the material inhomogeneity
a mathematical model is presented in the present study to control the light propagation in an inhomogeneous media. the method is based on the identification of the optimal materials distribution in the media such that the trajectories of light rays follow the desired path. the problem is formulated as a distributed parameter identification problem and it is solved by a numerical met...
متن کاملA New Electron Energy-loss Straggling Algorithm in Mcnp
A new algorithm for energy-loss straggling in MCNP is demonstrated. An approximate but accurate energy-loss moment-preserving differential cross section is used in conjunction with single event Monte Carlo simulation through each condensed history step to show that highly accurate energy spectra, leakage currents, and dose profiles can be obtained. This new approach provides a viable and even p...
متن کاملthe impact of skopos on syntactic features of the target text
the present study is an experimental case study which investigates the impacts, if any, of skopos on syntactic features of the target text. two test groups each consisting of 10 ma students translated a set of sentences selected from advertising texts in the operative and informative mode. the resulting target texts were then statistically analyzed in terms of the number of words, phrases, si...
15 صفحه اولFast ion surface energy loss and straggling in the surface wake fields.
We have measured the stopping powers and straggling of fast, highly ionized atoms passing through thin bilayer targets made up of metals and insulators. We were surprised to find that the energy losses as well as the straggling depend on the ordering of the target and have small but significantly different values on bilayer reversal. We ascribe this newly found difference in energy loss to the ...
