Abstract

High-energy-resolution magnetic spectrometer measurements have been used to determine the width of the 9.641 MeV 12C, 3 excited state. The width is found to be 48(2) keV with an R-matrix analysis. This would correspond to 30% of the Wigner limit, indicating a significant α-particle content to the state. This is a marked improvement on results of earlier studies that yielded 34(5) keV.
