我们研究了原子核中包含（y，¯p）和（p,p）反应，并检查了对¯p湮灭机制的敏感性。我们发现，与只考虑¯p湮灭的单一体机制相比，在原子核中包含多个体湮灭机制明显减少了这些反应的横截面。这表明¯p产生反应对¯p湮灭比直接¯p湮灭反应更敏感，并使产生实验成为研究原子核中¯p湮灭复杂机制的有用工具。
We study the inclusive (y,¯ p) and (p,p) reactions in nuclei and check the sensitivity to the¯p annihilation mechanisms. We find that including the many body annihilation mechanisms in nuclei reduces appreciably the cross section of these reactions with respect to the evaluation considering only the one body mechanism of¯p annihilation. This shows that the¯p production reactions are more sensitive to¯p annihilation than the direct¯p annihilation reactions and makes the production experiments very useful tools to investigate the complex mechanisms of¯p annihilation in nuclei.
