    DETERMINATION OF LIFETIMES OF EXCITED STATES IN NEUTRON-RICH O-20 ISOTOPE FROM EXPERIMENT WITH THE AGATA plus PARIS plus VAMOS SETUP
    (JAGIELLONIAN UNIV PRESS, 2019) Ciemala, M.; Ziliani, S.; Crespi, F.; Leoni, S.; Fornal, B.; Maj, A.; Beckers, M.
    An experiment aiming at measuring lifetimes of the second 2(+) excited states in neutron-rich C and O isotopes was recently performed at the GANIL laboratory, in France. In these nuclei, recent ab initio calculations provide a detailed description of the nuclear excited states, predicting a strong sensitivity of the electromagnetic transition probabilities to the details of the nucleon-nucleon interactions, especially in connection with the role played by the three-body (NNN) forces. Thus, the measurement of 2(+) states lifetimes in this region will be a stringent test of the importance of including the NNN forces in describing the electromagnetic properties of selected nuclear states. This contribution reports on the status of the experimental analysis for the case of lifetimes in O-20.

    SPECTROSCOPY OF NEUTRON-RICH C, O, N AND F ISOTOPES WITH THE AGATA plus PARIS plus VAMOS SETUP AT GANIL
    (JAGIELLONIAN UNIV PRESS, 2019) Ziliani, S.; Ciemala, M.; Crespi, F.; Leoni, S.; Fornal, B.; Maj, A.; Beckers, M.
    Recent ab initio calculations pointed out the importance of the three-body terms of the nuclear interaction, in the description of the structure of n-rich systems. The state lifetimes in light n-rich carbon and oxygen nuclei have been predicted to be sensitive to the three-body terms and, in this context, an experiment, aiming at the measurement of these lifetimes, was performed in GANIL in July 2017 with the AGATA and PARIS arrays coupled to the VAMOS++ magnetic spectrometer. Details on the AGATA preliminary data analysis are presented.
