Abstract

We report on the first observation of hypernuclear γ transitions using germanium detectors. Using a large-acceptance Ge detector system, we observed two γ transitions in ⁷ΛLi, the spin-flip M1(3/2⁺→1/2⁺) transition at 689±4 keV and the E2(5/2⁺→1/2⁺) transition at 2050±2 keV (preliminary). The strength of the ΛN spin-spin interaction is derived from the energy of the former transition. As for the latter transition, B(E2) was measured to be 3.9±0.6±0.4 e²fm⁴ (preliminary), which indicates a shrinkage of the nuclear size of ⁷ΛLi from ⁶Li and confirms "glue-like role" of Λ.
