What is the maximum electron energy in a neutron beta-decay?
Correct answer: B. 783 keV
- A. 783 eV
- B. 783 keV
- C. 783 GeV
- D. 783 Tev
Explanation
Beta-decay occurs when, in a nucleus with too many protons or too many neutrons, one of the protons or neutrons is transformed into the other. In beta-minus decay, a neutron decays into a proton, an electron, and an antineutrino. The maximum electron energy in neutron beta-decay is hence 783 keV.

About Nuclear Physics
Atomic nuclei contain protons and neutrons, with nuclear size, mass defect and binding energy describing their stability. The work covers alpha, beta and gamma decay, decay equations, half-life and decay rate, along with radiation safety and medical applications such as imaging, radiotherapy and tracers.
