Abstract

Characteristic $γ$ radiation produced in the reaction ${}^{7}{Li} (K^{-}, π^{-} γ)$ at a kaon momentum of 1.7 GeV/c has been analyzed with Ge(Li) detectors. A transition at 789±4 keV is a candidate for a new hypernuclear $γ$ -ray line. The intensity of this transition corresponds to a c.m. forward-angle production cross section of 48±12 μb for the reaction ${}^{7}{Li} (K^{-}, π^{-} γ)$ . Several $γ$ -ray lines observed with ${}^{6}{Li}$ , Be, B, C, and O targets could be ascribed to ordinary nuclear transitions.
