Suppose we think of fission of a `._(26)^(56)Fe` nucleus into two equal fragments, `._(13)^(28)Al`. Is the fission energetically possible ? Argue by working out Q of the process. Give `m(._(26)^(56)Fe)=55.93494 u` and `m(._(13)^(28)Al)=27.98191 u`.

`Q = m(""_(26)^(56) Fe) - 2m (""_(13)^(28)Al) = 26.90 MeV`, not possible.
