FISSION RESONANCE INTEGRALS OF U-233, U-235, Pu-239, AND Pu-241

Technical Report ·
OSTI ID:4008097

The fission resonance integrals of 233/U, /sup 235/U, /sup 239/Pu, and / sup 241/Pu were measured relative to B, Li, and Au standards by fission counting. The fission resonance integrals of /sup 233/U, /sup 235/U and /sup 239/Pu were also measured relative to an In standard by the fission product gamma counting technique. Weighted averages of the fission resonance integrals above a 0.45 ev cut-off (including the 1/v contribution) obtained from this and other measurements are 761 plus or minus 17, 277 plus or minus 5, 324 plus or minus 9, and 541 plus or minus 14 barns for /sup 233/U, /sup 235/U, /sup 239/Pu, an d /sup 241/Pu, respectively.
