摘要

采用薄靶对能量0.962.74MeV质子在纯度为99.99%铝上的160非卢瑟福弹性背散射截面进行了测量。质子束由21.7MV串列加速器提供

测量仪器采用金硅面垒探测能谱仪。实验中最低能区进入卢瑟福弹性散射能区

测量结果用图表形式给出

并与以前发表的结果进行了比较。所测量数据可供从事背散射分析技术的有关人员参考。

Abstract

In recent years

research on films containing the element aluminum

such as AlNi3 memory alloy and aluminum ions implanted modified film

has become very common. If proton backscattering analysis is to be used for investigating aluminum content and distribution profiles in the films

the elastic backscattering cross sections of protons from aluminum for a wide energy range are very useful data. The present paper reports our measured results of differential elastic backscattering cross sections of 0.96-2.74MeV protons from aluminum of 99.99% purity at a laboratory scattering angle of 160. Analyzed beams of proton were provided by a 21.7MV tandem accelerator at Lanzhou University. The lowest proton energy in the experiment is in the Rutherford backscattering energy region. The measured cross sections are given in tabular and graphical forms and compared with previous graphical data. The presented data should be useful for those who are interested in the reaction 27Al(p

p)27Al near 160 in a wider energy region.
