With a high energy-resolution of {delta}E=21 keV in the {sup 34}S({sup 3}He,t){sup 34}Cl measurement at 0 degree sign and at 140 MeV/nucleon, strengths of Fermi and Gamow-Teller (GT) transitions between T{sub z}=+1 and T{sub z}=0 states were studied, where T{sub z} is the z component of isospin T. The corresponding isospin-symmetric transitions connecting T{sub z}=-1 and T{sub z}=0 states can be studied in the {sup 34}Ar {beta}{sup +} decay. The strengths of corresponding GT transitions were compared up to the excitation energy (E{sub x}) of 3.1 MeV. A good agreement was observed for the two strong transitions to states around E{sub x}=3 MeV, while a disagreement of 40% was observed for a weaker transition to a low-lying state.
