Fission yield curve
WebThe abundance pattern of the fission products in these particles resembled the shape of the mass-yield curve for the thermal neutron-induced fission of uranium-235, except for the facts that cesium-hl37 and strontium-90 were markedly depleted and the yields near the symmetric fission region appeared to be somewhat enhanced. WebThe U 235 fission yield curve for uranium fuel rods from mass number 143 to 160 has been measured, utilizing mass spectrometric techniques. Eight percentage yields are …
