EC and α decays of 235Am have been studied using a gas-jet coupled on-line isotope separator. Excited states in 235Pu have been established for the first time by means of γ-ray spectroscopy following the EC decay of 235Am. The deduced log ft value suggests that the ground state of 235Am should have the π5/2-[523] configuration. The α-γ coincidence result has revealed that the π5/2-[523] state in 231Np populated by the favored α transition of 235Am is located at < 15 keV, which allows us to precisely determine the Qα value of 235Am.
