Abstract :
An NaI(Tl) spectrometer system has been installed to measure the cross section of a radiative neutron-capture reaction of a nucleus at an astrophysically relevant energy of between 10 and 500 keV. The system consists of two large anti-Compton NaI(Tl) spectrometers and a new data-taking system. The spectrometer can detect a discrete γ-ray emitted promptly from a neutron-capture state to its low-lying state, and the data-taking system can transfer events with much higher rates, about 30-times higher, compared to the existing system.
