Measurement of neutron capture cross sections of Pd-107 at J-PARC/MLF/ANNRI

• The capture cross sections of 107Pd were measured with an NaI(Tl) spectrometer.
• Measurements were performed at J-PARC/MLF/ANNRI.
• The accelerator was run in a special operational mode called “single bunch” mode.
• The capture cross sections of 107Pd were derived from the thermal to keV energies.

Measurements of the neutron capture cross sections of 107Pd were carried out at the Materials and Life Science Experimental Facility (MLF) of the Japan Proton Accelerator Research Complex (J-PARC). Gamma-rays were detected with an NaI(Tl) spectrometer of the Accurate Neutron–Nucleus Reaction Measurement Instrument (ANNRI). The neutron capture cross sections were determined by the time-of-flight method in the neutron energy region from the thermal to keV energies.
