Abstract

The analysing power A_y( theta ) for ¹²C(n,n) ¹²C elastic scattering and for inelastic scattering to the first excited state (J^pi=2⁺, Q=-4.44 MeV) of ¹²C was measured at 18.2 MeV. A pulsed polarised neutron beam was produced via the ²H(d,n)³He polarisation transfer reaction. The A _y data, together with published cross sections, were analysed in the framework of the spherical optical model and in the coupled-channels formalism. A phase-shift analysis at 18.2 MeV gives supporting evidence for a broad ⁵/₂⁺ resonance. The ¹²C recoil kerma factors and values for the n+¹²C reaction cross section were deduced and compared with previous estimates and predictions.
