“…The mean of deviations between experimental and theoretical ranges obtained from three computer codes HB, RANGE and TRIM was evaluated and found to be 3.0%, 4.2% and 1 1 .l %, respectively. This work has qualitatively supported some earlier findings (Dwivedi, 1991;Dwivedi et al, 1993b;Ghosh et al, 1988Ghosh et al, , 1994Jain et al, 1989Jain et al, , 1991Kocsis et al, 1993;Saxena and Dwivedi, 1990) barring a few cases (Ghosh et al, 1994;Kocsis et al, 1993) that the computer code 'RANGE' may be used to derive fairly reliable values of heavy ion ranges in complex solids. Though the validity of theoretical ranges of heavy ions from computer code 'RANGE' has been tested below 20 MeV/u, the program from Henke and Benton is applicable up to 500 MeV/u.…”
