Abstract : The Ni K absorption spectra in five nickel-rich solid solutions and the intermediate phases Ni3Al, NiAl, and NiAl3 are presented. By considering the absorption process taking place within the nickel atoms, variations in the fine structure of the absorption spectra are interpreted in terms of the possible electronic structures of nickel atoms. It is demonstrated that the electronic structure changes markedly with composition in the a solid solution in a way suggestive of covalent bond formation. (Author)
