Abstract: For the first time, the electronic structure of Ni, Cu, and Zn in Ni$_{0.27}$Cu$_{0.73}$, Ni$_{0.18}$Cu$_{0.51}$Zn$_{0.31}$, and Cu$_{0.66}$Zn$_{0.34}$ and some other chemical compounds has been studied using the method of shifts of the $K$ X-ray lines. Statistically reliable shifts (from the positions for the metal) of all diagram $K$-lines of Ni have been found for both alloys, whereas the shifts of the $K$-lines of Cu and Zn (also from the positions for the metals) are close to zero for all the alloys. For the first time, estimates have been obtained for the 3$d$- and/or 4$s$-facsimiles, i.e., shifts of all diagram lines caused by the removal of one 3$d$- and/or 4$s$-electrons. On the basis of these facsimiles, the found shifts of the $K$-lines of Ni in Ni$_{0.27}$Cu$_{0.73}$ and Ni$_{0.18}$Cu$_{0.51}$Zn$_{0.31}$ lained by the transference of $\lesssim$ 0.10 and 0.15 of its 4$s$-electron to 3$d$-band of the same atom.
