Low-lying intruder and tensor-driven structures in As 82 revealed by β decay at a new movable-tape-based experimental setup

The beta decay of Ge-82 was re-investigated using the newly commissioned tape station BEDO at the electron-driven ISOL (isotope separation on line) facility ALTO operated by the Institut de Physique Nucleaire, Orsay. The original motivation of this work was focused on the sudden occurrence in the light N = 49 odd-odd isotonic chain of a large number of J
