The radionuclide 11C decays according to The maximum
Chapter , Problem 57(choose chapter or problem)
The radionuclide 11C decays according to The maximum energy of the emitted positrons is 0.960 MeV. (a) Show that the disintegration energy Q for this process is given by Q ! (mC # mB # 2me)c 2 , where mC and mB are the atomic masses of 11C and 11B, respectively, and me is the mass of a positron. (b) Given the mass values mC ! 11.011 434 u, mB ! 11.009 305 u, and me ! 0.000 548 6 u, calculate Q and compare it with the maximum energy of the emitted positron given above. (Hint: Let mC and mB be the nuclear masses and then add in enough electrons to use the atomic masses.)
