The proton-rich nucleus 33Ar has been studied by detailed proton and gamma-ray spectroscopy at the low-energy facility of SPIRAL at GANIL. Proton and gamma-ray singles and coincidence measurements allowed to establish a quasi complete decay scheme of this nucleus. By comparing the proton intensity to different daughter states, tentative spin assignments have been made for some of the states of 33Cl. The Gamow-Teller strength distribution is deduced and compared to shell-model calculations and a quenching factor is determined. States close to the isobaric analogue state are searched for with respect to isospin mixing.
