    High-spin level structure of 35 S
    (American Physical Society, 2014) Aydın, Sezgin; Ionescu-Bujor, M.; Recchia, Francesco; Lenzi, Silvia M.; Bouhelal, Mouna; Bazzacco, Dino B.; Bizzeti, P. G.; Bizzeti-Sona A.M.
    The nucleus 35S has been studied by in-beam ?-ray spectroscopy using the 24Mg(14N,3p) fusion-evaporation reaction at Elab=40 MeV. A level scheme extended up to J?=17/2+ at 8023 keV and J?=13/2- at 6352 keV has been established. Lifetimes of six excited states have been determined by applying the Doppler shift attenuation method. The experimental data have been compared with the results of large-scale shell model calculations performed using different effective interactions and model spaces allowing particle-hole excitations across the N=Z=20 shell gap. © 2014 American Physical Society.

    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. M.; de Angelis, G.; Deloncle, I.; Farnea, E.; Gadea, A.; Gottardo, A.; Goutev, N.; Haas, F.; Huyuk, T.; Laftchiev, H.; Lunardi, S.; Marinov, Tz.

    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.

    High-spin structure and intruder excitations in Cl-36
    (American Physical Society, 2012) Aydın, Sezgin; Recchia, Francesco; Ionescu-Bujor, M.; Gadea, Andrés; Lenzi, Silvia M.; Lunardi, Santo; Ur, Calin Alexandru; Bazzacco, Dino B.; Bizzeti, P. G.; Bizzeti-Sona, A. M.; Bouhelal, M.; de Angelis, G.; Deloncle, I.; Farnea, E.; Gottardo, A.; Haas, F.; Huyuk, T.; Laftchiev, H.; Mengoni, D.; Menegazzo, R.; Michelagnoli, C.; Napoli, D. R.; Sahin, E.; Singh, P. P.; Tonev, D.; Valiente-Dobon, J. J.
    Excited states up to J(pi) = 11(-) at 10 296 keV and J(pi) = 10(+) at 10 707 keV have been populated in the odd-odd Cl-36 nucleus using the Mg-24(N-14,2p) fusion-evaporation reaction at E-lab = 31 MeV. Twenty new states and 62 new gamma transitions have been identified by employing gamma-gamma and gamma-gamma-gamma coincidences. Lifetimes have been investigated by the Doppler shift attenuation method. The experimental data have been compared with the results of large-scale shell-model calculations performed using different effective interactions and model spaces allowing particle-hole excitations across the N = Z = 20 shell gap.
