Measurement of the ratio of the fission cross sections of 239Pu and 242Pu to that of 235U is reported. The sources of neutrons were the 7Li(p,n)7Be and D(d, n)3 He reactions. The ratio of the masses of the samples was determined by low geometry alpha counting and from relative thermal fission rates. The results are compared with other measurements.
