Abstract
The 270 chromospheric emission lines of Feii ranging between 2000 and 3200 Å observed by Skylab at a height of 4″ (2900 km) above the limb of the quiet Sun are analyzed by the emission curve of growth method, using newly calculated gf-values. It is derived that the excitation temperature is 7.2 × 103 K and that the turbulent velocity is consistent with the previous results that the microturbulent velocity is lower than 10 km s−1 in the cool (<104 K) region of the chromosphere.
