When you do not understand does not mean it must be nonsense.
It just mean you do not understand.

You could guess I cannot catch all language word plays.

Concerning momentum change, not momentum itself, it does not matter.

For momentum conservation idea one need not them.
One need them for momentum calculation.

I do not deny that.

BTW,gamma  photons are not produced at reaction
2 1H --> 2He, as it is extremely unstable isotop with negative binding
energy, neither at conversion to deuterium.

They are produced in 2nd major reaction D + H --> 3He,
and by electron positron anihilation.

What did not you understand in sensence
Kinetic energy follows here momentum conservation. ?
