Beta-decay spectroscopy with beams of laser-polarised nuclei at VITO ISOLDE
Beta-decay spectroscopy is a powerful experimental tool for studying complex phenomena that emerge in exotic neutron-rich nuclei. A novel approach to beta-decay experiments, pioneered by a group from the University of Osaka [1,2], has recently been implemented at the VITO beamline [3] at CERN ISOLDE. The new end station, called DeVITO [4], has been integrated with a laser polarisation setup [3], enabling beta-decay spectroscopy studies with spin-oriented nuclei. This unique combination allows for measurements of beta-particle emission asymmetry in coincidence with gamma rays and/or neutrons, providing a solid foundation for unambiguous spin-parity assignments for states involved in allowed beta transitions [1, 2]. During the seminar, I will present the experimental setup used in the first DeVITO experiment [4], its physics motivation, and preliminary results.
