Measurement of neutron capture cross section of Li-7 at J-PARC / MLF / ANNRI

We have measured the 7Li(n,γ)8Li 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 γ rays from the 7Li(n,γ)8Li reaction with sufficient signal-to-noise ratio.
