Abstract
LSS based computed electronic stopping power values have been compared with the corresponding measured values in polymers for heavy ions with Z = 5–29, in the reduced ion velocity region, vred ≤ 1. Except for limited vred ∼ 0.6–0.85, the formulation generally shows significantly large deviations with the measured values. The ζ factor, which was approximated to be ∼Z11/6, involved in LSS theory has been suitably modified in the light of the available experimental stopping power data. The calculated stopping power values after incorporating modified ζ in LSS formula have been found to be in close agreement with measured values in various polymers in the reduced ion velocity range 0.35 ≤ vred ≤ 1.0.
