The fact that the reaction ³⁷Cl +$ \bar{v}_{\mathrm{e}} $ $\to$³⁷Ar + e^- is not observed whereas the reaction p +$ \bar{v}_{\mathrm{e}} $ $\to$ n + e⁺ is observed is understandable in terms of the conservation of A)baryon number B)energy C)lepton number D)charge E)angular momentum

Question

Quizplus · Accepted Answer

The observed reaction involves the creation of an electron and a neutrino, both of which have lepton number L = 1. The disappearance of the electron and neutrino in the unobserved reaction would violate lepton number conservation. Therefore, the only possible choice is (C) lepton number conservation.
