我们从理论上研究了介质对（）反应中产物的影响，使用了最优费米平均过程，该过程描述了核子在核中有能壳反应条件下的费米运动。结果表明，中截面具有很强的能量依赖性和角依赖性，这对核靶上（）反应中超核态产生谱的形状和大小有显著影响。在一个费米气体模型中讨论了（）反应在准自由生产中的应用。
We study theoretically medium effects onproduction in the () reaction, using the optimal Fermi-averaging procedure, which describes the Fermi motion of a nucleon on the on-energy-shellreaction condition in nuclei. The results show the strong energy and angular dependencies of the in-mediumcross section, which affect significantly the shape and the magnitude of the production spectrum for-hypernuclear states in the () reaction on a nuclear target. The application to thequasifree production via the () reaction on atarget is also discussed in a Fermi gas model.
