论文摘要
我们建议从理论上扩展最佳的费米平均过程，以计算中等内部的$ k^-n \至π^ - λ$振幅，用于放热（$ k^ - $，$，$π^ - $）在核上对核的反应的反应，以造成损失的波冲突，并通过$ seplatie the the the the ted-wave Impaster的浪潮，并考虑到$ ke seprant的繁殖量 - $π^ - $ MESON。 $^{12} $ c（$ k^ - $，$π^ - $）$^{12}_λ$ C反应的角度分布，其中动量转移为$ q \ lessim $ 80 mev/$ c $ $ p_k = $ p_k = $ 800 mev/$ c $ $ 800 mev/$ c $ in $π^ - $ forward Direction估算了Extender exterder exterder exterder temend exterder。结果表明，计算出的角度分布与数据的分布非常吻合，并且该扩展是一种成功的处方，使得可以在我们的框架中描述近乎记录的反应中的反应横截面，例如（$ k^ - $，$，$，$，$π^ - $）。
We propose to extend the optimal Fermi averaging procedure theoretically in order to calculate an in-medium $K^-n\to π^- Λ$ amplitude for the exothermic ($K^-$, $π^-$) reaction on nuclei in the framework of a distorted-wave impulse approximation, taking into account the local momentum transfer generated by semiclassical distorted waves for $K^-$ and $π^-$ mesons. Angular distributions for the $^{12}$C($K^-$, $π^-$)$^{12}_Λ$C reaction in which a momentum transfer is $q \lesssim$ 80 MeV/$c$ at $p_K=$ 800 MeV/$c$ in the $π^-$ forward direction, are estimated by applying the extended procedure. The result shows that the calculated angular distributions are in good agreement with those of the data, and this extension is a successful prescription making it possible to describe the reaction cross sections in near-recoilless reactions such as ($K^-$, $π^-$) in our framework.
