Abstract

The analyzing power $A_{y} (θ)$ for neutron elastic scattering from ${}^{12}C$ has been measured for 33 neutron energies between $E_{n} = 2.2$ and 8.5 MeV in the angular range from 25 $^{°}$ to 145 $^{°}$ in the laboratory system. The primary motivation for these measurements is the need for an accurate knowledge of $A_{y} (θ)$ for ${}^{12}C$ $(n, n)$ ${}^{12}C$ elastic scattering to enable corrections to high-precision neutron-proton and neutron-deuteron $A_{y} (θ)$ data in the neutron-energy range below $E_{n} = 30$ MeV. In their own right, ${}^{12}C$ $(n, n)$ ${}^{12}C$ $A_{y} (θ)$ data are of crucial importance for improving both the parametrization of $n −$ ${}^{12}C$ scattering and our knowledge of the level scheme of ${}^{13}C$ . The present $A_{y} (θ)$ data are compared with published data and previous phase-shift-analysis results.
