摘要

根据LSS理论计算和采用Rutherford背散射实验方法（RBS），测定和分析了低能重离子（110 keV Fe,+,）注入小麦种子后离子达到的深度。测定结果和计算结果相符合，平均射程约为115 nm。还从核物理学和辐射化学考虑了离子的热穗效应（thermal spike effect）、亚激发电子的位移以及次级电子的热化尾巴（thermalization tail）等可能造成作用范围的扩大，并对它们进行了初步的理论估算。

Abstract

According to LSS theory the depth of low energy heavy ions implanting into wheat seeds was calculated in the paper. On the other hand, the depth was also measured and analysed by RBS method. Both of the results were consistent with each other. The average range was about 115 nm. Possible effect ranges induced by thermal spike effect of the ions, subexcitation electron amplitude and thermalization tail of the secondry electrons were discussed in view of nuclear physics and radiation chemistry were respectively valued.
