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.
