Which of the following reactions utilizes deuterons to accelerate particles?

The correct choice indicates a reaction that involves deuterons, which are atomic nuclei consisting of one proton and one neutron. In the reaction represented by the choice, ( ^{20}\text{Ne} ) interacts with a deuteron to produce ( ^{18}\text{F} ) and an alpha particle.

This reaction specifically denotes a nuclear reaction type where a heavier nucleus, in this case, neon-20, is bombarded by a deuteron. The interaction leads to a nuclear transformation and the emission of an alpha particle, demonstrating how deuterons can effectively serve as projectiles or accelerators of other particles in nuclear reactions.

Overall, this reaction showcases the role of deuterons in facilitating nuclear processes, which is essential in the broader understanding of nuclear physics and applications such as PET imaging and radiopharmaceutical development.
