Nuclear decay properties of the neutron-deficient actinide isotopes ^{233,234,235,236}Am and ^237,238Cm have been investigated using a gas-jet coupled on-line isotope separator at the JAERI tandem accelerator facility. Alpha-decays of ^233,235,236Am and ^237,238Cm produced in the ⁶Li-induced reactions on ^233,235U and ²³⁷Np targets have been observed with unambiguous mass identification, and the new isotopes ²³³Am and ²³⁷Cmhave been identified for the first time. Alpha-particle energies, Q_α values, half-lives and α-branching intensities were determined and the observed α decays of ²³³Am and ²³⁵Am are regardedas the favored tr.
