Emission core widths of K Ca H line in the umbra and penumbra of 9 sunspots and in their vicinity are measured. All sunspots are located near the solar disc center. Data on variation of widths Wt~ along the 'mean' sunspot radius are obtained. Values W~ in the umbra and penumbra centers are equal or
Grevesse and Swings (1968) and, independently, Lambert et al. (1969) identified the [Ca HI 4s z S1/2-3d z D3/2 line at 7323.90/~ in the Sun. Unfortunately, this line usually appears as an asymmetry in a much stronger telluric water line at 7323.97 β’ and is difficult to resolve, as evidenced by the d
intensity factors for bands of the C-A transition of the A1F molecule are calculated. A reinvestigation for the lines of (0, 0) band of the C-A system in sunspot spectra is suggested, so as to resolve the question~tble existence of A1F absorption lines in sunspots.
