Abstract: Carbon stopping-power (SP) data for heavy ions (HIs), obtained around Bohr velocities, revealed remarkably lower values than those predicted by the SRIM/TRIM calculations/simulations. An attempt was made to extract the elastic (collisional) and inelastic (electronic) components from available SP data. A problem is that essentially total SP is measured in experiments, whereas electronic SP values, presented as the results, are obtained by the subtraction of the calculated collisional component values from the measured ones. At high HI reduced velocities (V/v0)/Z_HI^2/3 > 0.3 (V and v0 are HI and Bohr velocities, respectively, and Z_HI is the HI atomic number), the collisional component can be neglected, whereas at Bohr velocities it becomes comparable to the electronic one. These circumstances were used to compare the experimental data with SRIM/TRIM calculations/simulations and to extract empirically the collisional SP component.
