THE INDEPENDENT YIELD OF $sup 96$Nb IN THE THERMAL NEUTRON FISSION OF $sup 233$U, $sup 235$U, AND $sup 239$Pu
The independent yields of 23 hr niobium-96 in the thermal neutron fission of U/sup 233/, U/sup 235/, and Pu/sup 239/ we re measured to test Wahl's hypothesis. Results expressed as fractionsof the total chain yiehd are (1.0 plus or minus 0.2)10/sup -3/, (9.S plus or minus 2.0)10/sup -5/, and (6.2 plus or minus 1.0)10/sup -4/ for U/sup 233/, U/sup 235/, and Pu/sup 23/ >s/sup 9/ respectivsly. A plot of these yields on the charge distribution curve shows that the plutonium fission results fall considerably below the curve, just as do ths uranium results. This would indicats that the favored 50-42 proton split is at any rate not an important factor in causing the low yield of 23 hr Nb/sup 96/. The low yield may be explained by the shont half-life of the isomer of niobium-96 which makes the independent yield very difficult to determine. (N.W.R.)
