The neutron-capture cross sections of
Cm and
Cm were measured in the energy range of 1-300 eV with an array of large germanium detectors in the ANNRI at J-PARC/MLF. The resonances at around 7.7 and 16.8 eV of
Cm and 4.3 and 15.3 eV of
Cm were observed in capture reactions for the first time. The uncertainties of the obtained cross sections are 5.8% at the top of the first resonance of
Cm and 6.6% at that of
Cm. Resonance analyses were performed for low-energy ones using the code SAMMY. The prompt
-ray spectra of
Cm and
Cm were also obtained. Eight and five new prompt
-rays emitted were observed in the
Cm(n,
) and
Cm(n,
) reactions, respectively.
