What statement accounts for alpha-particles having discrete energies, while beta-particles show a continuous range of energies?
- ABeta-particles have a much smaller mass than alpha-particles which means beta-particles can be emitted with a larger range of velocities.
- BOnly alpha-particles experience repulsion from the nucleus which is dependent on the number of protons in the nucleus.
- COnly beta-particles are emitted with another lepton and some energy is transferred to the other lepton.
- DOnly the energy of alpha-particles is discrete because the composition of alpha-particles is always the same.
