Consider the fission of by fast neutrons. In one fission event, no neutrons are emitted and thefinal end products, after the beta decay of the primary fragments, are  and Calculate Q for this fission process. Therelevant atomic and particle masses are

m =238.05079 u
m =139.90543 u
m = 98.90594 u



Answer -

In the fission of, 10 β− particlesdecay from the parent nucleus. The nuclear reaction can be written as:

It is given that:

Mass of a nucleusm1 = 238.05079 u
Mass of anucleus m2 = 139.90543 u
Mass of a nucleus, m3 = 98.90594 u
Mass of a neutronm4 = 1.008665 u

Q-value of the above equation,

Where,

m’ = Represents the correspondingatomic masses of the nuclei

= m1 − 92me

= m2 − 58me

= m3 − 44me

= m4

Hence, the Q-value of the fissionprocess is 231.007 MeV.
