Baryon decays and gamma-spectroscopy of hypernuclei

Abstract

The applicability of (K−,π−γ) - and (K−,π−Nγ)-reactions on13,14C and14,15N nuclei to the study of γ-transitions in primary and daughter Λ-hypernuclei is discussed. The intensity of γ-deexcitation ofΛ13C state |SΛ ⊗12C(15·11 MeV; 1+1): 1/2+〉 has been shown to be comparable with the intensity of baryon decay. Isospin selection rules are used to distinguish excitation energy ranges of primary hypernuclei, where the identification of the secondary γ-lines is probable.
