New measurements of the main nik emission lines are presented for nickel-aluminium alloys with up to 50 at% al. The shifts of the nikalpha/sub 1/ line of the alloys are found to be negative with respect to pure nickel, contrary to previous measurements by nemoshkalenko et al. (see abstr. A41614 of 1971). In addition to a possible charge transfer between the constituent atoms, the importance of the crystallographic phase and order is emphasized in the interpretation of the spectra. Complete filling of the d band in the nial compound is not supported by the results.
