$ 1979Ca16: First observation of 230Fr. Production cross sections for various isotopes were measured for a variety of target materials using ISOL methods. Measured T1/2.
$ 1987Ku04: Studied rotational bands in 230Ra populated by β- decay of 230Fr. Observed transitions placed in the Kπ=0+ ground-state band, Kπ=0- octupole band, and Kπ=2+ γ-vibrational band. Measured Eγ, Iγ, γγ coindidence, and T1/2.
$ 1990Me13: Searched for β-delayed fission in neutron-rich nuclei, which produced negative results. Placed limits on delayed-fission probabilities in neutron-rich actinide nuclei.
