Photon scattering in the solar ultraviolet lines of He i and He ii

Observations made with the Coronal Diagnostic Spectrometer (CDS) onboard the Solar and Heliospheric Observatory (SOHO) are used to investigate the behaviour of the intensities of the emission lines of He i, He ii and O iii at the quiet Sun-centre and at θ= 60° towards the equatorial limb. The aim is...
