In-beam γ-ray spectroscopy with fast beams of rare isotopes: Experiments to elucidate the structure of very exotic atomic nuclei

Accelerator facilities dedicated to the efficient production of particle beams of rare isotopes allow experimenters to employ new techniques that can make meaningful measurements of experimental observables with very low beam rates. This talk illustrates the state of experiments that employ in-flight separated beams and exemplifies the additional scientific reach provided by the large luminosity gains that arise in particle-γ coincidence experiments.
