Abstract
Stopping force formula for heavy ions with ZHI=3-36, in the energy region ∼0.2–3.0 MeV/n, is developed. For this, fitting parameters involved in effective charge parameterization of Hubert et al. formulation are modified. Other parameters, used for stopping force calculations, are computed by utilizing Ziegler’s fitting formulae. To check the reliability/validity of the present stopping force formula, the computed results are compared with the recently measured values. The comparison reveals that the predicted values are in good agreement (within experimental errors) with the recently measured values. The study is significantly important because low energy ions are widely used in material science particularly in ion implantation/irradiation along with other fields like atomic and molecular physics, health physics, bio-science and medical science etc. In addition, the study is also important to understand the fundamental aspects involved in interaction of ion with matter. The predicted values based on the present formula can be used as an input parameter for all those experiments where these combinations are used.
