Abstract
The status of a project to measure spin-isospin responses of neutron drip-line nuclei using a new low-energy neutron detector, PANDORA (Particle Analyzer Neutron Detector Of Real-time Acquisition), is reported. The performance of PANDORA was characterized by the He-6(p, n)Li-6 reaction in inverse kinematics at the HIMAC facility in Chiba. Observation of the strong transition to the ground state in Li-6 is discussed. Preliminary results of Li-11(p, n)Be-11 and Be-14(p, n)B-14 experiments in inverse kinematics at RI Beam Factory (RIBF) of RIKEN Nishina Center are also presented including the exotic decay channel of Be-11 -> Li-9 + d. Details of the experimental setup based on PANDORA and the SAMURAI large-acceptance magnetic spectrometer, as well as the combined data-acquisition system are described. The neutron-gamma discrimination capability of PANDORA was evaluated, Figure-of-Merit (FoM) values higher than those found in the literature for similar materials were derived from experimental data.
