Extended optimal Fermi averaging for near-recoilless $\Lambda$ production in the ($K^{-}$, ${\pi }^{-}$) reaction on nuclei

Toru Harada, Yoshiharu Hirabayashi

We propose to extend the optimal Fermi averaging procedure theoretically in order to calculate an in-medium $K^{-}n\to {\pi }^{-}\Lambda$ amplitude for the exothermic ($K^{-}$, ${\pi }^{-}$) reaction on…
