我们系统地计算了弹丸与靶核之间初始态静电相互作用对低能反质子-质子和反质子-核湮灭截面的增强效应。该计算旨在未来比较不同目标上的反中子和反质子湮灭率，以提取纯同位旋通道。
We calculate, in a systematic way, the enhancement effect on antiproton-proton and antiproton-nucleus annihilation cross sections at low energy due to the initial state electrostatic interaction between the projectile and the target nucleus. This calculation is aimed at future comparisons between antineutron and antiproton annihilation rates on different targets, for the extraction of pure isospin channels.
