    Electromagnetic transition strengths in S-33
    (IOP Publishing Ltd, 2014) Dimitrov, B. I.; Goutev, N.; Gavrilov, G. Tz.; Tonev, D.; Petkov, P.; de Angelis, G.; Recchia, F.; Aydın, S.
    An experiment using the Doppler Shift Attenuation Method was performed for S-33 at Laboratori Nazionali di Legnaro using the multi-detector array GASP. Excited states were populated in the fusion-evaporation reaction Mg-24(N-14, alpha p)(33) S. The data were analyzed using the Differential Decay Curve Method with gates set on the shifted component of a directly feeding transition thus eliminating the problem of the unobserved feeding. Reliable and precise lifetimes were determined and the data derived for the reduced transition probabilities are going to be compared to the predictions of shell model calculations.

    High-spin states and lifetimes in S-33 and shell-model interpretation in the sd-fp space
    (American Physical Society, 2017) Aydın, Sezgin; Ionescu-Bujor, M.; Gavrilov, G. Tz.; Dimitrov, B. I.; Lenzi, Silvia M.; Recchia, Francesco; Tonev, Dimitar; Bouhelal, Mouna; Kavillioglu, F.; Pavlov, P.; Bazzacco, D.; Bizzeti, P. G.; Bizzeti-Sona, A.

    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.
