Eric--
I am looking at the Knolls Atomic Power Laboratory, Chart of the Nuclides,
Thirteenth Addition Revised as of July 1983. This chart does not include
proton capture cross sections. I do not believe I have seen proton capture
cross sections for any isotopes. The cross section would have to be a function
of the proton energy. The thermal neutron cross section of the proton is 0.333
barns and its integral cross section is 0.150 barns.

I think you have the decay scheme for Ni-59 wrong. It has a 76,000 year
half life and decays by electron capture as you said.
It's good that you seem to know your way around these nuclear transitions.
That makes you and Robin and a few others who can keep the rest of us honest.
The data I have indicate no gamma activity, in the transition to the Cu-59
nucleus.
I'm thinking of this reaction:

What data are you using? Do they include proton capture cross sections? Up
to now I have only been able to work out the Q values but have had no insight
into the cross sections. The Exfor cross section data are hard to make sense
of.
