abstract

  • 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 quasicomplete 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 analog state are searched for with respect to isospin mixing.
