Energy and width of ${}^{11}\mathrm{O}(\mathrm{g}.\mathrm{s}.)$

I have used a potential model and a convolution procedure to compute energy-dependent widths for simultaneous ${}^{11}\mathrm{O}\left(\mathrm{g}.\mathrm{s}.\right)\to {}^9\mathrm{C}+2p$ decay. A Breit-Wigner shape calculated with those widths provides excellent agreement with recent experimental data.

Data points are the points from Fig. 1(b) of Ref. [1] with their background subtracted. Curves are Breit-Wigner shapes with energy-dependent widths: $E_0=4.7$, $\mathrm{\Gamma }\left(E_0\right)=2.17\mathrm{MeV}$ (dashed line), and $E_0=4.75\mathrm{MeV}$, $\mathrm{\Gamma }\left(E_0\right)=2.51\mathrm{MeV}$ (solid line).
