Thermal-neutron capture and fission cross sections and resonance integrals for curium-243

The thermal-neutron capture cross section and capture resonance integral for 243Cm have been measured in cobalt-monitored reactor irradiations of nearly isotopically pure 243Cm (99.94 percent) using cadmium filter techniques. The thermal-neutron absorption (capture plus fission) cross section and corresponding resonance integral for 243Cm have also been measured in a separate experiment relative to 248Cm. Values of sigma2200(n,γ) = 130.7 +- 9.6, sigma2200(n,f) = 609.6 +- 25.9, I(n,γ) = 214.7 +- 20.3, and I(n,f) = 1575 +- 136 b are reported
