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 7 Λ Li, 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 e 2 fm 4 (preliminary), which indicates a shrinkage of the nuclear size of 7 Λ Li from 6 Li and confirms ''glue-like role'' of Λ.
