摘要
根据Biersack角扩散模型,建立了计算MeV重离子在固体靶中的平均投影射程的方法。与新近发表的1.0MeV的In^+,Xe^+,Ta^+和1.0—2.0MeV的Pb^+在Si中的平均投影射程实验数据相比,本文计算值与实验值的最大偏离为8％,而Monte-Carlo(TRIM′86)和PRAL的计算值与实验值的最大偏离分别为23％和22％。这表明本文的计算在预言1.0—2.0MeV的重离子(In^+,Xe^+,Ta^+和 Pb^+)在固体靶(Si)中的平均投影射程是相当成功的。
Based on Biersack's angular diffusion model, an effective method was established for calculating the mean project range of MeV heavy ions in solid targets. The calculated values are compared with recent experimental data on the mean project range for 1.0 MeV In+, Xe+, Ta+ and 1.0-2.0 MeV Pb+ The maximum difference-between present calculated values and experimental data is less than 8%, but the maximum differences between experimental data and calculated values by TRIM 86 and PRAL are 23% and 22%, respectively- The results show that the present calculation procedure is sucsessful for predicting the mean projected range on 1.0-20 MeV such heavy ions as In+, Xe+, Ta+ and Pb+ implanted in solid target (Si).
