Abstract

We have started a series of experiments of hypernuclear gamma-ray spectroscopy using a germanium detector system called Hyperball. In KEK E419, we observed two gamma transitions in Li-7(Lambda), 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 e(2)fm(4) (preliminary). In BNL E930, we observed the E2(5/2(+), 3/2(+) --> 1/2(+)) transitionsof Be-9(Lambda) at around 3.05 MeV.
