What is the rest mass energies for electron, Ee, and positron, EP?
(a) Ee = 1.02 MeV, EP = 1.02 MeV
(b) Ee = 0.51 MeV, EP = 1.02 MeV
(c) Ee = 1.02 MeV, EP = 0.51 MeV
(d) Ee = 0.51 MeV, EP = 0.51 MeV
I got this question in unit test.
The origin of the question is Pair Productions in chapter Quantum Physics of Engineering Physics I
