Title: β-decay spectroscopy studies with beams of spin-polarised nuclei at VITO
Speaker: Ilaria Michelon (CERN and UniGe, CH)
Abstract: β-decay spectroscopy is a powerful experimental tool for studying complex phenomena emerging in exotic neutron-rich nuclei. A novel approach to β-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 β-decay spectroscopy studies with spin-oriented nuclei. This unique combination allows measurements of β-particle emission asymmetry in coincidence with γ rays and/or neutrons, providing a solid foundation for unambiguous spin-parity assignments for states involved in allowed β transitions [1, 2].
This contribution will cover details of the experimental setup used in the first DeVITO experiment [4], as well as its physics motivation, and preliminary results from the commissioning experiments with neutron-rich K isotopes.
