参考答案:
Neither hydrogen nor deuterium can emit an $\alpha$ particle. Hydrogen has only one nucleon (a proton) in its nucleus, and deuterium has only two nucleons (one proton and one neutron) in its nucleus. Neither one has the necessary four nucleons (two protons and two neutrons) to emit an $\alpha$ particle.
