Question

In the Proton cycle, the hydrogen and deuteron fuse to form ___________

(a) Deuteron

(b) Tritium

(c) Helium – 3

(d) Helium – 4

The question was asked during an online exam.

My question is taken from Nuclear Fusion topic in section Quantum Physics of Engineering Physics I

Answer 1

Correct answer is (c) Helium – 3

To explain I would say: The process is as follows: ^2D + ^1H -> ^3He + Q X 2

The deuteron combines with a proton to yield Helium-3.
