WebFission yields have been calculated assuming as a first approximation that they are proportional to the product of the level densities of a pair of binary fission products. The level densities have been calculated with the simplified shell-model methods of … WebNuclear Binding Energy Curve. The binding energy curve is obtained by dividing the total nuclear binding energy by the number of nucleons. The fact that there is a peak in the binding energy curve in the region of stability near iron means that either the breakup of heavier nuclei (fission) or the combining of lighter nuclei (fusion) will yield nuclei which …
