Electronic stopping power of polymers for heavy ions in the ion energy domain of LSS theory
چکیده انگلیسی

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.
