Abstract:
Information on the isotopic composition of chemical elements in the Sun may be obtained by analysis of photospheric and sunspot spectra. It is shown that besides investigations performed on molecular lines, information on isotope abundances of some heavier elements may also be derived from atomic line studies. A discussion of the elements Tb, Sr, Sb and Eu are described. Studies of the solar isotopic composition of Cu from analysis of Cu I lines in photospheric spectra and CuH lines in sunspot spectra are described. Author Modified Abstract
