Coupling gamma-ray arrays to spectrometers: the way to better exploits radioactive beams

Abstract : The coupling of very efficient gamma-ray arrays with large acceptance (or highly selective) spectrometers in the context of radioactive beams has pushed away the limits and opened up new possibilities in nuclear physics studies. At GANIL the EXOGAM array (a large efficiency gamma-ray array) has been coupled to VAMOS (a large acceptance spectrometer) and to SPEG (a highly selective spectrometer) to study many different aspects of nuclear structure and reactions covering the whole nuclear chart: indeed, this combination has been used to study neutron rich nuclei toward 54Ca, neutron deficient Sn isotopes around A=103, heavy elements around Md and No, reaction mechanism using the borromean light He isotopes, the nuclear structure in the island of inversion around 32Mg, and many other examples in various domain and energy regime. This is also the case for the very efficient large BaF2 array “Château de crystal” which is frequently coupled to SPEG to study nuclear structure far from stability. In this talk, the various possibilities offered at GANIL with such a coupling will be given. In the future, AGATA will be installed at GANIL to exploit the beams produced by the SPIRAL2 facility. The scientific objectives motivating this installation will be discussed. Again, it is anticipated that this new generation array will be coupled to spectrometers to better exploit the future beams
