| Abstract: | Gamma-ray decays of the 12.71 and 16.11 MeV states of 12C are investigated in a coincidence study of the 10B(τ, pγ) reaction, and using the 163 keV 11B(p, γ) resonance. This information together with existing data on M1 transitions and stripping and pickup spectroscopic factors is used to determine the isospin mixing between the 12.71 and 15.11 MeV levels. A charge dependent mixing matrix element of 110 ± 30 keV is deduced. |
