H plus H plus beta equals D,
D plus another H make He-3,
He-3 plus He-3 is He-4,
Plus H and H left-over, flying free,
Ready to make some more.
Meanwhile, H plus H plus beta
Also makes a positron –
A positron and electron
Make a photon, plus another one –
And lots and lots of them will light the Sun.
‘He’ above is said with two syllables – Aitch-Ee.
