$T$ mixing and decay widths of first two $1^{-}$ states in ${}^{10}\mathrm{B}$

For the isospin-mixed $1^{-}$ states in ${}^{10}\mathrm{B}$, widths for deuteron and α decays provide an independent estimate of the amount of isospin mixing, which is consistent with results from γ decays. Analysis provides two solutions for the proton spectroscopic factors of the pure $T=0$ and 1 states.

Estimates of isospin mixing of first two $1^{-}$ states in ${}^{10}\mathrm{B}$: from γ decays to $1^{+}, T=0$ states, from γ decays to $0^{+}, T=1$ states, and from $d$ and α decays.
