Abstract

Using a large-acceptance germanium detector array (Hyperball), we have observed a spin-flip M1 γ transition between the ground-state spin doublet of ⁷ Li (3/2⁺ → 1/2⁺). The observed energy of 691.7 ± 0.6 (stat) ± 1.0 (syst) keV provides crucial information on the strength of the spin-spin interaction between a Λ and a nucleon. This is the first observation of well-identified hypernuclear γ transitions using germanium detectors.
