Feynman diagram for neutron capture

I am studying experimental methods for detecting neutrons. Having recently studied QFT, I wondered if there was a way to describe this type of process through a Feynman diagram.

For example for the process
$${}_{2}^3{rm He} + n longrightarrow {}_1^3{rm H} + p $$ if it is possible to describe this interaction in terms of quarks.

This question came to me trying to find a formal explanation of the resonances that the cross section presents as shown in the figure:
