The EC and α decays of neutron-deficient Am and Cm nuclei have been studied using a gas-jet coupled on-line isotope separator. Decay schemes of the EC decay of 235, 236Am have been constructed, and weak α decays of 233, 235, 236Am and 237, 238Cm have been observed. The efficiency of the on-line mass separation of Bk nuclei was measured to be ∼1%. The Qα values, α-decay partial half-lives, and proton-neutron configurations are discussed.
