It has been suggested that transmutation of actinide waste into fission products could be enhanced by using resonance fission of odd-odd target materials; those of interest are {sup 232}Pa, {sup 238}Np, and {sup 242}Am. Our technique for carrying out the measurement of the resonance fission cross section of short-lived materials has three steps: (1) We produce the sample by the (d,2n) reaction at the Los Alamos Ion Beam Facility. (2) We carry out fast radiochemistry to separate the odd-odd target of interest. (3) We measure the fission rate in a high intensity pulsed neutron beam produced by 800 MeV proton spallation. Using this technique, we have successfully measured the neutron-induced fission cross sections of 1.3 day {sup 232}Pa and 2.1 day {sup 238}Np, from 0.01 eV to 50 keV.
