Question

The radionuclide ¹¹C decays according to

The maximum energy of the emitted positron is 0.960 MeV. Given the mass values:calculate Q and compare it with the maximum energy of the positron emitted

Answer 1

The given nuclear reaction is:

m’ = Respective nuclear masses
If atomic masses are used instead of nuclear masses, then we have to add 6 me in the case of 'Cand 5 me in the case of 'B.

The value of Q is almost comparable to the maximum energy of the emitted positron.
