The interpretation of ion beam analysis data requires accurate simulation of the output spectra. The recent trend towards Monte Carlo (MC) simulation, particularly for techniques using heavy ions, follows in recognition of limitations in traditional

Monte Carlo (MC) simulation can be used to simulate heavy ion elastic recoil detection analysis spectra, including the broadening and tailing effects of multiple and plural scattering, although it is very costly in terms of computer time. In this wor

This study investigates the performance of photon beam models in dose calculations involving heterogeneous media in modern radiotherapy. Three dose calculation algorithms implemented in the CMS FOCUS treatment planning system have been assessed and v

HIERDA spectra are complicated by the pronounced broadening and tailing effects that arise from the frequent plural and multiple scattering undergone by swift heavy ions in solids. The quantitative evaluation of these spectra is dependent on a clear

In Heavy Ion Elastic Recoil Detection Analysis (HIERDA), Rutherford scattering determines the number of scattered and recoiled ions that reach the detector. Because plural scattering is a major contributor to the spectrum and can mask important featu

Neutron total cross sections have been measured in the energy range of 20 to 45 MeV for Be, C, Al, Cu, and Zn. The typical accuracy was 1% to 2%. Results are compared with optical model calculations in which the only variable is the surface absorptio
