- Accelerator Laboratory, University of Helsinki, Haemeentie 100, SF-00550 Helsinki, Finland (FI)
The stopping power for {sup 24,26}Mg ions in 17 ({ital Z}=22--79) elemental solids has been studied in the energy region 0--1.0 MeV/nucleon by application of the Doppler-shift attenuation method. At velocities 2{ital v}{sub 0}{lt}{ital v}{lt}5{ital v}{sub 0} ({ital v}{sub 0} the Bohr velocity), the scaling factors 1.10 (Ti), 0.90 (V), 0.93 (Fe), 0.97 (Co), 0.99 (Ni), 1.03 (Cu), 1.05 (Ge), 1.05 (Nb), 1.15 (Mo), 1.05 (Pd), 1.08 (Ag), 1.09 (Hf), 1.07 (Ta), 1.05 (W), 1.05 (Re), 1.05 (Pt), and 0.96 (Au) to the commonly used empirical electronic stopping power by Ziegler, Biersack, and Littmark were determined to an accuracy of {plus minus}5%. At velocities {ital v}{lt}2{ital v}{sub 0}, much higher electronic stopping power and different velocity dependence than predicted by the empirical model were obtained. The electronic stopping power was determined to an accuracy of {plus minus}5%. The reduction of the nuclear stopping power due to the polycrystalline structure of the slowing-down materials was taken into account in the deduction of the electronic stopping power.
