Abstract

The double differential cross sections (DDCS) of electron emission in ionization of adenine molecule (C₅H₅N₅) induced by 5 MeV/u bare C ions are measured using the electron spectroscopy technique. Emission of electrons from adenine is measured in the energy range from 20 eV to 460 eV and in the angular range from 20° to 160°. The single differential cross sections (SDCS) and total ionization cross section (TCS) are deduced from the e-DDCS. The experimental results are compared with the prior form of the continuum distorted wave- eikonal initial state (CDW-EIS) model prediction. Overall, a very good agreement between the theory and experiment is observed.

5 MeV / u裸C离子在腺嘌呤分子电离中的电子发射

摘要

使用电子光谱技术测量由5 MeV / u裸C离子诱导的腺嘌呤分子（C ₅ H ₅ N ₅）电离中电子发射的双微分截面（DDCS）。在20 eV至460 eV的能量范围和20°至160°的角度范围内测量腺嘌呤电子的发射。从e-DDCS推导出单微分截面（SDCS）和总电离截面（TCS）。将实验结果与连续畸变波初始状态（CDW-EIS）模型预测的现有形式进行了比较。总体而言，在理论和实验之间观察到非常好的一致性。
