It is found that HelI 4686 ,is emitted in ithe same cold region of < 10000 K as hydrogen, metal and neutral helium emission lines. This conclusion is based on the finding that the observed width of 24686 is the same as the calculated width of 24686. The calculated width is derived from the observed

The excitation of the levels 21P, 31D, 51D, 61D and 71D of helium in quiescent prominences and the chromosphere is considered using the observations made during the
The transfer of radiation in filamentary prominences for a two-level atom was considered. Variation of the sources function with depth was calculated and is presented graphically in prominences of various optical thickness (TM = 10, 50, and 100) and degree of filamentation (3' = 1.0, 0.5, 0.1, and
Observations of a number of helium triplet (~.210830, 4713, 4471, 3889, 4026) and hydrogea (H),, g, r/, 0) emission line intensities in six quiescent prominences are presented. The regions of prominence and neighboring corona were raster-scanned by the telescope, and all lines were measured concurre
The paper deals with the excitation of the he[ium singlet level 2~P in the homogeneous and filamentary models of quiescent prominences with following parameters: the optical thickness at the limit of helium Lyman continuum ~,. = 0.1-100, T~ = 7000 K, n,. = 5 x 10~~ cm -3. Assuming a model He I atom
