The neutron-capture cross sections of $$^{112}$$Sn and $$^{118}$$Sn were measured by the time-of-flight method in the energy range from 10 meV to 2 keV with an array of germanium detectors in ANNRI at J-PARC. The preliminary results of the neutron-capture cross sections for $$^{112}$$Sn and $$^{118}$$Sn were obtained by normalizing the relative cross sections to the thermal cross section measured by Krane and to the evaluated value of JENDL-4.0 at the 47.05-eV resonance, respectively. Twelve new resonances for $$^{112}$$Sn were observed, whereas the 21.02-, 40.38- and 166-eV resonances for $$^{112}$$Sn and the 289-eV resonance for $$^{118}$$Sn which are listed on JENDL-4.0 and/or ENDF/B VII.1 were not observed. The prompt $$gamma$$-ray distributions gated at the $$^{112}$$Sn and $$^{118}$$Sn resonances were obtained. Twenty-three new prompt $$gamma$$-ray emissions were observed in the $$^{112}$$Sn (n,$$gamma$$) reactions.
