In this study the model suggested by Sugiyama has been developed and applied for the calculation of the stopping powers for nonrelativistic heavy ions in various target materials. Sugiyama's model has been expanded to low and high energy regions in our work. Analytical expressions are obtained in the modified BB stopping power formula for the effective charge and effective mean excitation energies. In the modified LSS formula, a quasi-molecule criterion has been applied to both the projectiles and the target atoms. Electronic excitation contribution, S e0 , and quasi-molecule contribution, S ei , to stopping power were found for a wide energy region. It is observed that in intermediate energy region both contributions have maxima. The stopping power due to excitation-ionization in the intermediate and higher energy region is found to be dominant, whereas quasi-molecule contribution is dominant in the lower energy region. The calculated results of stopping power are in good agreement with experimental data for various ions and targets within a few percent in a wide projectile energy range.

“…The energy calibration of the machine was made by measuring the γ-ray yields from the low energy resonances in the 19 F (p,  ) 16 O reaction. H + , H2 + , H3+ and 4 He + ion beams with average current of ~ 30 nA on the stopping target were used under high operation vacuum (mean pressure of about 10 -6 Torr) within the scattering chamber.…”

“…As stated, several methods based on the RBS technique and applicable in some particular cases, each presenting manifest advantages as well as mathematical constraints, have been proposed [16][17][18][19] to extract the stopping cross section values. However, these methods become less reliable at low projectile energies in the case of thick and low Z-targets for which the kinematics factor, k, amounts to less than 0.7. , of outgoing ions scattered at angle 2 = 165°.…”

“…This method (see next section) greatly facilitates the determination of the  (E) data, minimizing the associated systematic errors that mainly originate from the target thickness. The data for 4 He + ions determined from the front edges of the O patterns in the RBS spectra allowed us to extend our previous numerical method [19] for exploring the lower ion energy region. We also aimed at extracting the effective charge parameter, , for the 4 He + ions across the SIMOX target.…”

The stopping cross sections  (E) of silicon for protons and alpha particles have been measured over the velocity range (0.3-1.2) MeV/u from a Si//SiO2//Si (SIMOX) target using the Rutherford Backscattering Spectrometry (RBS) with special emphasis put on experimental aspects. A detection geometry coupling simultaneously two solid-state Si detectors placed at 165° and 150° relative to each side of the incident beam direction was used to measure the energies of the scattered ions and determine their energy losses within the stopping medium. In this way, the basic energy parameter, Ex, at the Si/SiO2 interface for a given incident energy E0 is the same for ions backscattered in the two directions off both the Si and O target elements, and systematic uncertainties in the  (E) data mainly originating from the target thickness are significantly minimized. A powerful computer code has been elaborated for extracting the relevant  (E) experimental data and the associated overall uncertainty that amounts to less than 3%. The measured  (E) data sets were found to be in fair agreement with H. Paul's compilation and with values calculated by the SRIM 06 computer code. In the case of 4 He + ions, experimental data for the -effective charge parameter have been deduced via scaling the measured stopping cross sections to those for protons crossing the same target at the same velocity and compared to the predictions of the SRIM 06 code. It is found that the -parameter values generated by the latter code slightly deviate from experiment over the velocity region around the stopping cross section maximum where strong charge exchanges usually occur.
