The photodisintegration cross section of the nucleus 92Mo is important for p-process nucleosynthesis. The superconducting electron accelerator ELBE at Forschungszentrum Dresden-Rossendorf provides the possibility to investigate photodisintegration with bremsstrahlung using the photoactivation technique. The reaction 92Mo(gamma,p)91Nb was studied using the decay of 91mNb with a 60.9 d half-life at ELBE [1]. Now the reaction 92Mo(gamma,n)91Mo has been probed using the new pneumatic delivery system to determine the activity of 91mMo (half-life: 65 s). Since the isomer 91mMo decays also into 91mNb it was necessary to measure this process to separate the (gamma,n) from (gamma,p) contributions.
