The spontaneous fission decay constant of plutonium-238 was measured by two methods: fission-track counting in mica and coincidence counting of the fission fragments in solid-state detectors. The efficiency of the mica track detector was determined by thermal column irradiation of the plutonium source-mica detector assembly and subsequent counting of tracks arising from plutonium-239 fission. The coincidence counting result was combined with a determination of the /sup 238/Pu alpha emission rate of the sample to obtain the spontaneous fission decay constant. The results of the two methods were lambda/sub sf/ = (4.75 +- 0.12) x 10/sup -19/ sec/sup -1/ and (4.9 +- 0.4) x 10/sup -19/ sec/sup -1/, respectively. 4 figures, 1 table. (auth)
