The operation of a new experimental apparatus called "Accurate Neutron-Nucleus Reaction measurement Instrument (ANNRI)" in the Material and Life science experimental Facility (MU) at the Japan Proton Accelerator Research Complex (J-PARC) has been started for neutroncapture crosssection measurements of minor actinides and long-lived fission products. As a part of the measurements, we have measured the time-of-flight spectra of palladium-105, 106, 107 and 108 with a "4 pi Ge spectrometer" installed at the ANNRI. We obtained preliminary results of the cross sections for palladium-107 and 105 in neutron energies ranging from 0.1 eV to 300 eV.
