EC and {alpha} decays of {sup 235}Am have been studied using a gas-jet coupled on-line isotope separator. Excited states in {sup 235}Pu have been established for the first time by means of {gamma}-ray spectroscopy following the EC decay of {sup 235}Am. The deduced log ft value suggests that the ground state of {sup 235}Am should have the {pi}5/2{sup -}[523] configuration. The {alpha}-{gamma} coincidence result has revealed that the {pi}5/2{sup -}[523] state in {sup 231}Np populated by the favored {alpha} transition of {sup 235}Am is located at <15 keV, which allows us to precisely determine the Q{sub {alpha}} value of {sup 235}Am.
