In-beam gamma-ray spectroscopy at the RIBF

In-beam gamma-ray spectroscopy is a powerful tool to investigate new excited states and the properties of very exotic nuclei. At the Radioactive Isotope Beam Factory (RIBF), it combines the in-flight BigRIPS fragment separator with an efficient gamma-ray spectrometer. Exotic beams produced by BigRIPS are incident on a secondary target at 100 to 250 MeV/nucleon for Coulomb excitation or secondary fragmention and knockout experiments. Secondary reaction products are identified by the ZeroDegree spectrometer. Details of the method are described alongside the performance of the gamma-ray spectrometers, first results, and prospects for future experiments and setups.
