The anomalous feature in ${}_{}{}^8{}_{}{}^{}\mathrm{Be}$ reported at $E_x\approx 0.6$ MeV has been investigated using ${}_{}{}^9{}_{}{}^{}\mathrm{Be}$($p$,$d$)${}_{}{}^8{}_{}{}^{}\mathrm{Be}$ at 14.3 and 26.2 MeV bombarding energy. Analyses of the spectral shape and transfer cross sections as a function of scattering angle are consistent with this feature being part of the $J^{\pi }=0^{+}$ ${}_{}{}^8{}_{}{}^{}\mathrm{Beg}$.s. Approximately 6% of the g.s. transfer strength is contained in the anomaly. Also, the line width observed for the $J^{\pi }=2^{+}$ level ($E_x=2.94\mathrm{}$ MeV) appears to be independent of bombarding energy for $E_p=14\mathrm{} \mathrm{to} 180$ MeV.
