The total neutron cross sections have been measured and resonance parameters determined for ²⁴³Cm, ²⁴⁵ Cm, and ²⁴⁶Cm from 0.01 to 30 eV and for ²⁴⁴Cm up to 90 eV. A total thermal neutron cross section at 0.0253 eV was determined for ²⁴⁴Cm of 23 ± 3 b and 2900 ± 450 b for ²⁴⁵Cm. Resonance absorption integrals of 2345 ± 470 b for ²⁴³Cm, 605 ± 40 b for ²⁴⁴Cm and 897 ± 180 b for ²⁴⁵Cm were calculated from the resonance parameters.
