| Zusammenfassung |
| In this paper we present the results of a
study of the effect of vibrationally excited oxygen, O*2,
and nitrogen, N*2, on the electron density, Ne,
and the electron temperature, Te, in the D and E regions. The
sources of O*2 are O-atom recombination, the
photodissociation of O3, and the reaction of O3 with O at
D region altitudes. The first calculations of O*2(
j) number densities, Nj, are obtained by solving
continuity equations for the models of harmonic and anharmonic oscillator energy
levels, j=1-22. It is found that day time values of Nj
are less than nighttime values. We also show that the photoionization of O*2
( j ≥ 11) by Lα-radiation has no influence on the
D region Ne. In the nighttime D region the
photoionization O*2 ( j ≥ 11) by scattered
Lα-radiation can be a new source of O+2.
We show that the N*2 and O*2
de-excitation effect on the electron temperature is small in the E region of the
ionosphere and cannot explain experimentally observed higher electron
temperatures. |
