EC and 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. 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.
