CAIE A-Level Physics 23.1.5 Nuclear Fission and Fusion

Practise defining nuclear fusion and fission, distinguishing the joining and splitting of nuclei and identifying which process occurs in a described reaction.

Exam points

define nuclear fusion and nuclear fission as nuclear processes
identify whether a described nuclear reaction is fusion or fission

[Maximum number: 1]

In one type of nuclear process, deuterium $\left({ }_{1}^{2} \mathrm{H}\right)$ undergoes the reaction

{ }_{1}^{2} \mathrm{H}+{ }_{1}^{2} \mathrm{H} \longrightarrow{ }_{2}^{3} \mathrm{He}+{ }_{0}^{1} \mathrm{n} .

State the name of this type of nuclear process.
