Showing Beta Decay (Feynman diagrams?)

[ShrodingersCat]

Would someone please tell me how I would show Strontium-90 decay into Yttrium 90(and emitting Beta particles)?
Would I need to use a Feynman diagram?
Thank you!

What do you mean with "show"?

Show that the decay is possible? Check the masses of the particles and see if energy conservation allows it. All other conservation laws are not an issue if you consider the regular beta decay.

Make a graph that looks like science and has some relation to the decay? A Feynman diagram is perfect.

Show what's going on in the decay? Good luck.
