Further investigation of the $\gamma$ -transitions in $^4_\Lambda$H and $^4_\Lambda$He hypernuclei


The γ-spectra induced by stopped K− mesons in 6Li and 7Li targets in coincidence with the accompanying charged pions and π0 mesons. The γ-line at (1.04 ± 0.04) MeV observed with charged pions was identified as a γ-transition in Λ4H, whereas the γ-line at (1.15 ± 0.04)_MeV observed with π0 mesons was ascribed to a γ-transition in Λ4He. Using these new values for the excitation energies of the 1+ levels of Λ4H and Λ4He hypernuclei, the phenomenological ΛN potential for the s-state interaction was recalculated.
