dE/dx and range of α-radiations in Al, Ti and Ni metallic foils

dE/dx and range of α-radiations in Al, Ti and Ni metallic foils have been measured using silicon surface barrier detector. These measured values have been compared with corresponding predicted values based on most extensively used formulations viz. Grande and Schiwietz (CasP), Northcliffe and Schilling, Benton and Henke, ICRU-49 report (ASTAR) and Ziegler et al. (SRIM). The aim of this comparison is to identify the formulation that shows good agreement with the presently measured values.
