STOPPING POWER FOR MEV C-12 IONS IN SOLIDS

The slopping powers for 0.3-6.4 MeV C-12 ions in C, Al, Ti, Cu, Nb and Ag have been measured with the transmission method. The experimental data on stopping power are compared with evaluated values using LSS th eory, ZBL semiempirical model predictions and previous experimental da ta. The results show that there is significant discrepancy between pre sent work and LSS theory; for C in Al, ZBL calculations quite agree wi th our measurements, yet for C in other stoppers, those cannot reprodu ce most of present experimental data; our work consists mostly with pr evious measurements. Moreover, present stopping power data exhibit app arent Zz-oscillation. (C) 1998 Elsevier Science B.V.
