AbstractAbstract
[en] The results of measurements of the 242Cm fission cross section by neutrons in the 0.1-1.4 MeV range are reported. Measurements have been performed at the pulse electrostatic accelerator using breakdown MOS detectors of fragments. The 242Cm fission anisotropy has been measured at neutron energies Esub(n)=63.0+-40 keV and 1000+-100 keV which turned to be equal to 1.03+-0.11 and 1.23+-0.11, respectively. The 243Cm fission barrier height is determined to be equal to 6.18+-0.05 MeV using neutron binding energy values Bsub(n)=5.67 MeV. The 243Cm fission barrier curvature with account of inelastic neutron scattering is equal to h/2πwsub(f)=680+-60 keV
