  The structure of the weakly-bound $^{26}_{\;\;9}$F$_{17}$ odd-odd nucleus,
produced from $^{27,28}$Na nuclei, has been investigated at GANIL by means of
the in-beam $\gamma$-ray spectroscopy technique. A single $\gamma$-line is
observed at 657(7) keV in $^{26}_{9}$F which has been ascribed to the decay of
the excited J=$2^+$ state to the J=1$^+$ ground state. The possible presence of
intruder negative parity states in $^{26}$F is also discussed.
