摘要
本文用能量分辨本领为2.40V的弯晶谱仪,对3MeV^(12)C^+轰击Al的K_aX射线进行了高分辨研究,测量了K壳层一个空位和L壳层多个空位产生X射线的相对强度比,测定平均电离几率(E_1,o)为0.312±0.002。对实验装置和方法作了较详细的介绍。
High-resolution studies of aluminum K0 x-rays produced by 12C+ beam at energy 3.0MeV have been performed with a crystal spectrometer.which energy resolution is 2.4eV. The relative intensity radios for the production of one K-shell and multple L-shell vacancies are measured. The average ion-
ization probabilities PL (Et, 0) is 0.312 ± 0.002. The experimental arf arrangments and methods are described in detail
