Abstract: In the present work we compared some new constants for the empirical relation of stopping powers of alpha particles in the energy range 4 􀀀 15Mev=amu for elements Al,Cu,Ge,Ag and Au obtained from calculation of empirical formula and measurements of stopping and range of ions in matter (SRIM-2000). The range formulas were obtained by directly integrating the stopping power formula of alpha particles and the values of the ranges for the elements are calculated and compared with SRIM-2000. The alpha energy losses have been obtained from calculation for the elements source using alpha particle target; such losses are deviated signi cantly from SRIM-2000 result. The deviation suggested that the stopping powers and range given from SRIM-2000 is too small.These relations have been also used to nd out stopping powers and ranges in semiconductors. i
