Carbon Elastic and Inelastic Stopping-Power Components for Heavy Ions at Bohr and Higher Velocities / R.N.Sagaidak // Atoms [Electronic resource]. – 2023. – Vol.11, No.6. – P.86. – URL: https://doi.org/10.3390/atoms11060086. – Bibliogr.:40.

Carbon stopping power (SP) data for heavy ions (HIs), obtained around Bohr velocities, revealed remarkably lower values than those predicted using the SRIM/TRIM calculations/simulations. An attempt was made to extract the elastic (collisional) and inelastic (electronic) components from the available SP data obtained in experiments. A problem is that essentially, total SP is measured in experiments, whereas electronic SP values, usually presented as the results, are derived via the subtraction of the calculated collisional component from the measured values. At high HI reduced velocities (𝑉/𝑣0)/𝑍2/3HI≳0.3 (V and 𝑣0 are HI and Bohr velocities, respectively, and 𝑍HI 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 SP data with the SRIM/TRIM calculations/simulations and to empirically obtain corrections to the collisional and inelastic SP components.
