Neutron-deficient americium and curium isotopes with half-lives $$leq$$10 min have been produced with the tandem accelerator, and their EC and weak $$alpha$$ 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 $$alpha$$ 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.

EC and $$alpha$$ decays of neutron-deficient americium, curium, and berkelium nuclei have been studied using the JAERI on-line isotope separator. Decay schemes of $$^{235, 236}$$Am have been established for the first time, and proton-neutron configurations in $$^{235, 236}$$Am and $$^{235, 236}$$Pu have been determined. $$alpha$$ transitions observed in $$^{233, 235}$$Am were found to be the favored transitions between the $$pi 5/2^{-}[523]$$ Nilsson states. $$Q_{alpha}$$ values of $$^{237, 238}$$Cm have been determined. Nuclear structure, deformation, and atomic masses for these nuclei were discussed.
