摘要: Isospin mixing between the 12.71-MeV, ${1}^{+}$, $T=0$ and 15.11-MeV, $T=1$ levels in $^{12}\mathrm{C}$ is measured utilizing two different direct reactions. A consistent value (${\ensuremath{\beta}}^{2}\ensuremath{\sim}0.01$) obtained from both isospin-forbidden reaction $^{12}\mathrm{C}(d,{d}^{\ensuremath{'}})^{12}\mathrm{C}^{*}$ comparison of yields analog reactions $^{13}\mathrm{C}(d,t)^{12}\mathrm{C}^{*}$ (15.11 MeV) $^{13}\mathrm{C}(d,h)^{12}\mathrm{B}$ (0.00 MeV). This implies a charge-dependent matrix element these approximately 250 keV.
