$\Delta \mathit C$ = 2 VIA MIXING
Allowed in second-order weak interactions, e.g. mixing.
$\vert{}{\mathit m}_{{{\mathit D}_{{1}}^{0}}}–{\mathit m}_{{{\mathit D}_{{2}}^{0}}}\vert{}$ = $x\Gamma $ ($92$ $\pm12$) $ \times 10^{8}$ $\hbar{}$ s${}^{-1}$
($\Gamma _{{{\mathit D}_{{1}}^{0}} }$ $-$ $\Gamma _{{{\mathit D}_{{2}}^{0}} })/\Gamma $ = 2$\mathit y$ $0.0106$ $\pm0.0016$      (S = 1.1)
