Abstract
The collisional incoherent scatter spectral theory of Woodman is extended to the T
e
/T
i
> 1 case by using its equivalent electron- and ion-Gordeyev integrals in existing collisionless spectral models. A collisional
spectral model for T
e
/T
i
> 1 is needed in the interpretation of F region incoherent scatter returns obtained at small magnetic aspect angles.
