A beam of protons is directed at ⁷₃Li nuclei, producing ⁸₄Be nuclei. What particles are emitted in this process?

1. alpha particles
2. beta particles
3. gamma photons
4. neutrons

Correct answer: gamma photons

Solution

In the reaction where protons collide with lithium nuclei to form beryllium, the excess energy from the reaction can be released in the form of gamma photons, which are high-energy electromagnetic radiation.
