Descripción
We report the first reliable measurement of the nebular [O i] λ
5577 Angstroms emission line in the Orion nebula. Diagnostic diagrams
based on the 5577 [O i], 6300 [O i], 3467 [N i], 5197 [N i], 5200 [N i]
emission lines indicate that the bulk of the nebular emission in the
partially ionized zone of the Orion nebula is produced in regions with
low to moderate electron densities (2 x 103 -- 4 x
104 cm-3) and with electron temperatures in the
9000 to 11000 K range. This result permits to estimate the relative
importance of the physical mechanisms that produce the [Fe II] emission
lines.
