A set of CsI(pure) crystals have been tested for use as an electromagnetic calorimeter for π0 detection in photonuclear reactions at photon energies below 1.2 GeV. Performances of the calorimeter including energy and position resolution are studied by using the electron and tagged-photon beams at the INS-Tokyo electron synchrotron. In the first experiment for the nuclear coherent π0 photoproduction carried out at INS, a π0 mass resolution of 7 MeV (rms) has been obtained in the π0 energy region between 0.5 and 1.0 GeV.
