I've been told the following is incorrect, but I can't really see how.
Consider the fission event described by the equation 235U+n→93Rb+140Cs+3n
The energy released is given by Q=Δmc2=(mU+mn−mRb−mCs−3mn)c2=(mU−mRb−mCs−2mn)c2
and writing the nuclear masses in terms of the masses of their constituent nucleons less than nuclear binding energy we find Q=BRb+BCs−BU
You could then estimate these binding energies using the SEMF giving a value of roughly Q=145MeV
(in reality it should be something like 200MeV). However I'm just concerned about whether or not the general method is correct or not. Thanks in advance.
