The decay of a neutron into a proton and electron (n $\rarr$ p + e^-)is not allowed because of which one of the following conservation laws? A)electric charge B)spin angular momentum C)energy D)lepton number E)Both B and D are correct.

Question

Quizplus · Accepted Answer

The decay of a neutron into a proton and electron violates the conservation of lepton number, as it does not account for the necessary balance in leptons (neutrons and protons are baryons, not leptons). It also violates the conservation of spin angular momentum, as the spins of the particles involved do not add up correctly to conserve angular momentum.
