$\beta$-rays

Vedclass · Answer

(B) The spectrum of $\alpha$-particles and $\gamma$-rays is discrete (line spectrum) because they are emitted with specific,fixed energy levels corresponding to the transitions between nuclear energy states.In contrast,the $\beta$-decay process involves the simultaneous emission of an electron and an antineutrino (or a positron and a neutrino). The energy released in the decay is shared between the $\beta$-particle and the neutrino in a continuous range,resulting in a continuous energy spectrum for $\beta$-rays.
