The neutron capture cross sections of 129I and 127I were measured at the ANNRI beamline of J-PARC. The time-of-flight
experimental technique together with the neutron filtering system were applied to determine the cross section for neutron
energies from the thermal to the keV neutron regions. In the present work, alongside the cross section data, the results of
a resonance shape analysis with the REFIT code are also included.
