[en] A Computer program RADELI is described to calculate the moments of the range and deposited energy distributions for light ions in amorphous solids. The scheme of the classical work by Schioett and by Sigmund and Weissmann is followed, but more accurate approximations are used. The physical problem is described and the formulae necessary for the evaluation are presented. A detailed description of all subprograms contained in RADELI is given. Methods to construct a distribution from its moments are available but are not discussed in this note. (author)
