Your reply got me interested enough to look it up. yes, a high-energy gamma photon can cause neutron ejection: Photoneutron

The overall cross section for N14 is about 96 mb, but the threshold is pretty high, 24 MeV.
I guess a gamma ray pulse could do it, but at 24 MeV those photons would penetrate pretty deep, the primaries and secondaries would dose up the surface, I think.
I don’t have access to MCNP right now, that would give a clue.
