Description
We have started a series of experiments of hypernuclear γ-ray spectroscopy using a germanium detector system called Hyperball. In KEK E419, we observed two γ transitions in 7ΛLi, the spin-flip M1(((3)/(2))+ → ((1)/(2))+) at 689±4 keV and the E2(((5)/(2))+ → ((1)/(2))+) at 2050±2 keV (preliminary), where B(E2) was measured to be 4.1±0.6±0.5 e2fm4 (preliminary). In BNL E930, we observed the E2(((5)/(2))+, ((3)/(2))+ → ((1)/(2))+) transitions of 9ΛBe at around 3.05 MeV
