Scattering cross-sections and partial kerma factors for neutron interactions with carbon at 20<E_n<65 MeV

New measurements of differential elastic and inelastic neutron scattering from ¹²C at E_n=20.8, 22, 24 and 26 MeV are presented and analysed in terms of both spherical and deformed optical model potentials. Results of these analyses are compared with other recent differential and total cross-section measurements in order to obtain a consistent representation of the energy dependence of neutron scattering over a broad energy range. Heavy ion recoil kerma factors are calculated and compared with earlier measurements and estimates of these quantities.
