Low-energy spin excitations on polycrystalline LaFeAsOF samples have been studied by inelastic neutron scattering. The 
-integrated dynamical spin susceptibility 
"(
) at 11 meV decreases with increasing fluorine content 
across the phase transition from antiferromagnetic to superconducting phases. For superconducting samples, a peak in "() develops at = 
below 
, accompanied by its reduction below . Fe 3
orbital contribution on the dynamical spin susceptibility and the electron scattering between 
and 
Fermi surfaces are discussed.
