The shifts of Fraunhofer lines of different chemical elements in a homogeneous medium with a plane monochromatic progressive adiabatic sound waves are derived. The calculations indicate that lines of neutral elements (6 ~< ;go ~< 14) with lower excitation potentials Zo~ = 0-2 eV are red shifted, tho
The relative intensity of two CI lines at 1993.6 β’ and 1657.4 A, observed in the limb spectrum of the sun, is a factor 2.6 β’ 10 a larger than that expected if both lines were optically thin. It is shown that the observed intensity ratio may be explained in terms of the transfer of photons from 2 165
