What is Partial Gamma-production?

Hi

I am currently looking at some literature for the production of different radioactive nuclei under the bombardment of protons on Copper. I found something called partial γ-ray production cross-sections and I am wondering what this means. I know that cross-sections generally describe the probability of a nuclear reaction occurring but I don't fully understand this concept. Can you help me?

Regards

Looking at that publication, I think it is a description for all "n+nucleus -> nucleus + n + gamma + whatever" processes.

So it describes the probability that a nuclear reaction will produce a prompt gamma with a certain energy or is it any prompt gamma in general?

Example:
65Cu(p,n+γ(E=1200keV))65Zn - the partial γ-ray production cross-sections will thus describe the probability for this γ with this particular energy being emitted? Or does it describe the total gamma radiation from this transition?

If the energy is given like that, the number should correspond to photons with that energy.
Your process gives photons with well-defined energy.
