  Photon-induced reactions during the astrophysical p- (or gamma-) process
occur at typical temperatures of 1.8 < T9 < 3.3. Experimental data of
(gamma,n), (gamma,p), or (gamma,alpha) reactions - if available in the relevant
energy region - cannot be used directly to measure astrophysical (gamma,n),
(gamma,p), or (gamma,alpha) reaction rates because of the thermal excitation of
target nuclei at these high temperatures. Usually, statistical model
calculations are used to predict photon-induced reaction rates. The relations
between experimental reaction cross sections, theoretical predictions, and
astrophysical reaction rates will be critically discussed.
