Upcoming Seminars

  • April 25, 2018 at 15:15 in FYS3. Xiaofei Yang (Peking University, China): Investigating nuclear structure of exotic isotopes by laser spectroscopy 

    High resolution laser spectroscopy can access to multiple nuclear properties of ground/isomeric states of radioactive nuclei far from stability, such as nuclear spins, nuclear magnetic and quadruple moments and charge radii [1]. These fundamental properties of exotic nuclei provide important information for the investigation of the nuclear structure in different regions of nuclear chart.

    The nuclear structure in several key regions of the nuclear chart can be investigated, by using two laser spectroscopy techniques CRIS and COLLAPS at ISOLDE, for example the structure of neutron-rich isotopes in the Ca region and in the Ni region. Currently, several experiments are on-going focusing on nuclear structure studies in these two regions [2-3].

    Multiple nuclear structure information has been achieved from the nuclear spins, moments and charge radii of neutron-rich Zn isotopes [2], which will be discussed in detail here. Introduction to on-going experiments on neutron-rich K, Sc and Ge [3] isotopes at COLLAPS and CRIS will be followed, together with some preliminary future research plans.
