Consider the fission of `"_92^238U` by fast neutrons. In one fission event, no neutrons are emitted and the final end products, after the beta decay of the primary fragments, are `"_58^140Ce` and `"_44^99Ru` . Calculate Q for this fission process. The relevant atomic and particle masses are m( `"_92^238U`) =238.05079 u m(`"_58^140Ce` ) =139.90543 u m( `"_44^99Ru`) = 98.90594 u
