Abstract
It is shown that the elementary theory of line broadening by collision damping provides adequate explanation of the various bifurcations of the empirical solar curve of growth. The apparent dependence of damping constant of a line on the parity of its lower level also follows. Applications are made to other stars and some early laboratory results by Babcock of pressure shifts in FeI are qualitatively explained.Keywords
