摘要: 研究表明,TRIM程序运算结果与实验测量离子注入种子的射程分布数据相差甚远.本文根据种子微结构的特点,综合考虑多种因素,设计种子微结构模型和运算程序,用Monte-Carlo仿真不同能量(110 keV,20 keV,200 keV)、不同注量(2×1016 ions·cm-2,5×1016 ions·cm-2,1017 ions·cm-2,2×1017 ions·cm-2)的Fe+注入花生、彩棉、小麦种子的射程分布,结果显示本设计程序仿真的结果与实验测量数据较为吻合.所获得的注入离子与种子微结构相互作用的随机抽样模拟运算方法,为离子注入与生命体相互作用的理论研究提供新的思路.

Abstract: Current study shows that range distribution of ions implantated into plant seeds obtained with TRIM program are far from experimental data. According to characters of microstructure of plant seeds, microstructure models and calculation programs are designed. With Monte-Carlo simulation range distributions are calculated for iron ions implanted into peanut, color cotton and wheat seed at different energies (110 keV, 20 keV, 200 keV) and different doses (2×1016 ions·cm-2, 5×1016 ions·cm-2, 1017 ions·cm-2, 2×1017 ions·cm-2). The results agree well with experimental results. A random sampling simulation method is obtained for interaction between implantation ions and seed microstructure, which provides an idea for theoretical study of interaction between implantation ions and organisms.

Key words: Iron ions implantation, plant seed, Monte-Carlo simulation, range distribution
