Dr Tungate works on laser spectroscopy of radioactive isotopes to measure their ground state properties,- size, deformation, magnetic moment and spin. This requires the production of short-lived nuclear species, their extraction from the reaction chamber and the formation of an ionic beam for interrogation by a narrow band width laser beam. This work is performed at the IGISOL Facility at the University of Jyväskyä and ISOLDE at CERN. Dr Tungate has been a co-author on over 100 papers.
