    The structure of the S-33 nucleus was investigated in the Mg-24(N-14, alpha p) fusion-evaporation reaction using a 40-MeV N-14 beam. The level scheme was extended up to an excitation energy of 11.7 MeV and spin 19/2+. Lifetimes of the intermediate-and high-spin states have been investigated by the Doppler shift attenuation method. Data were compared with different shell-model calculations where effective interactions involving two main shells, the sd and the fp, are used.

    Level-scheme investigation of S-33
    (IOP PUBLISHING, 2014) Gavrilov, G. Tz.; Goutev, Nikolay; Dimitrov, B. I.; Tonev, Dimitar; Petkov, Pavel; de Angelis, Giacomo; Recchia, Francesco; Aydın, Sezgin
    An angular correlation experiment was carried out for S-33 at Laboratori Nazionali di Legnaro with the gamma-ray detector array GASP. The reaction used was Mg-24(N-14,alpha p)S-33 at a beam energy of 40MeV. An analysis of DCO ratios and triple gamma coincidences was performed. So far, a new level depopulated by 3 gamma -ray transitions has been found and its spin was determined. The work for further extension of the level scheme is in progress.
