The abundances of the elements in the solar photosphere-VII. Zn, Ga, Ge, Cd, In, Sn, Hg, Tl and Pb
Abstract
A detailed account is presented of the limited number of Fraunhofer lines which are attributable to the heavier elements with ground state configurations of S2, s2p or s2p2. The Oxford photoelectric spectrometer was used to obtain new measurements of the equivalent width for selected lines of Zn I, Ge I, Cd I, In I and TI I. A thorough discussion is given of the available expe1imental and theoretical oscillator strengths. The following abundances are obtained on the standard scale where log N(H) = : logN(Zn) = logN(Ga) = logN(Ge) = 3'32 logN(Cd) = logN(In) = 1.71 logN(Sn) = 1.71 logN(Hg) < logN(Tl) 0.2 logN(Pb) =
