Abstract

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 ⁷_ΛLi, 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 ⁹_ΛBe at around 3.05 MeV.
