Beta rays cannot specifically target alpha rays or individual nuclei due to the nature of particle interactions. While it is possible to accelerate a group of electrons to collide with a group of helium-4 nuclei, the interactions are not precise or targeted. The outcome of such collisions is unlikely to yield significant or interesting results. The fundamental properties of beta and alpha particles limit the ability to achieve specific targeting. Overall, the discussion emphasizes the challenges in manipulating these particles for targeted interactions.
