The structure of the 33 S nucleus was investigated in the 24 Mg(14 N,αp) fusion-evaporation reaction using a 40-MeV 14 N 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.
