Decay spectroscopy is an essential tool for probing the nuclear structure of exotic nuclei and for investigating the fundamental properties associated with the weak interaction described by the Standard Model and beyond.
The ISOL technique (ISOLDE, ALTO, IGISOL, etc.) generates low-energy beams of neutron- or proton-rich nuclei with a considerable purity. The beams produced in this way can be implanted in a thin band, allowing particles (such as β, proton, conversion electron, etc.) from decay to escape and reach the detectors with a minimum of scattering and energy loss. These experimental set-ups, known as decay stations, are highly versatile and include a range of detectors arranged around the implantation point, such as HPGe detectors (γ), plastic scintillators (β), TETRA or MONSTER (neutron), COeCO (conversion electron), TAGS (γ), etc.
