n + energy

Solution:

Concept:

Two lighter nuclei combine to form a heavier nucleus with the release of energy.

Explanation:

Deuterium

{}^2_1\mathrm{H}

and tritium

{}^3_1\mathrm{H}

are both light hydrogen nuclei.

They fuse together to form a helium nucleus and a neutron.

The nuclear equation is:

{}^2_1\mathrm{H} + {}^3_1\mathrm{H} \rightarrow {}^4_2\mathrm{He} + {}^1_0\mathrm{n} + \text{energy}

Since two small nuclei combine into a larger nucleus, this process is called nuclear fusion.
