The suggestion by Mordechai and Fortune, that the 8.95 MeV level in ${}_{}{}^{19}{}_{}{}^{}\mathrm{F}$ is the ‘‘missing’’ ${\mathrm{}(11/2)\mathrm{}}^{\mathrm{-}}$ member of the $K^{\pi }$${=(1/2)\mathrm{}}^{\mathrm{-}}$ band, is not acceptable when account is taken of the intraband γ-ray transition rates. The experimental evidence suggests that there is no single ${\mathrm{}(11/2)\mathrm{}}^{\mathrm{-}}$ state with a pure $p^{\mathrm{-}1}$(sd${)}^4$ configuration, but rather that configuration mixing takes place.
