Neutron-deficient americium and curium isotopes with half-lives 10 min have been produced with the tandem accelerator, and their EC and weak decays have been successfully measured through an on-line isotope separation. Decay schemes of $^{235,236}$ Am have been established, and proton-neutron configurations in the parent and daughter nuclei have been determined. Observed transitions in $^{233,235}$ Am were found to be the favored transitions between the $pi 5/2^{-}[523]$ Nilsson states. Information on nuclear structure, deformation, and atomic masses in this region were obtained.
