The Hubert et al, formulation for stopping power calculations has been exte
nded below its recommended range of validity, i.e. 2.5-500 MeV/n. It has be
en established that the extended formulation for projectiles with Z = 3-35
provides a good agreement with the experimental data for elemental targets
(6 less than or equal to Z less than or equal to 79) and complex materials
e.g. CR-39, LR-115, Mylar, Kapton, polycarbonate and Havar in the energy ra
nge 0.5-2.5 MeV/n. (C) 2001 Elsevier Science B.V. All rights reserved.
