The new neutron-deficient americium isotope 233Am produced via the 233U(6Li, 6n) reaction has been identified using the JAERI on-line isotope separator (JAERI-ISOL) coupled to a gas-jet transport system. The α-decay of 233Am and its subsequent α-decay chain have been observed in the mass-233 fraction. The half-life and α-particle energy of 233Am have been determined to be 3.2 ± 0.8 min and 6780 ± 17 keV, respectively. From these results and a deduced α-decay branching ratio, the observed α-decay is regarded as a favored transition.
