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