摘要：
We have measured the Li-7(n, gamma)Li-8 reaction at Accurate Neutron-Nucleus Reaction Measurement Instrument (ANNRI) installed at the Material and Life science experimental Facility in the Japan Proton Accelerator Research Complex (J-PARC / MLF). In this experiment, we used intense pulsed neutron beam provided by J-PARC / MLF and high performance Ge spectrometer, which is one of the main detectors of the ANNRI. We clearly detected gamma rays from the Li-7(n, gamma)Li-8 reaction with sufficient signal-to-noise ratio.
