EMISSION LINE IDENTIFICATION
Line No. 1
The most accurate measurement on this line is that of
Jian-sheng et al. (1981)
who give its wavelength as 4712.1±0.5 Å. We identify this line in the context
of the PLS model as the He I line 4713.14 2^3Po - 4^3S (mult. 12). The line is undergoing
laser action which gives rise to its great strength.
Line No. 2
No accurate wavelength for this line is available. The measured values
range from 5411 to 5428 Å (omitting the value of
Walsh et al., 1984).
Possible candidates for its identification are O I 5408 (mult. 53), O I 5410 (mult. 51, 52) and
S II 5428 (mult. 6).
Line No . 3
Again no accurate value for the wavelength is available. Reported values
range from 5957 to 6023 Å. Good candidates for its identification are Si II 5979
(mult. 4), O I 5991-95 (mult. 44), S II 5996 (mult. 13), N I 5999, 6008 (mult. 16),
and Al II 6000, 6002, 6006 (mult. 93). Clearly, more accurate wavelengths for line
Nos.2 and 3 are required for their identification.
