Abstract—Potential shifts induced by the Madelung potential in various molecular cluster regions were calcu-
lated using the muffin-tin approximation. Nickel and zinc oxides were used as examples to consider interrela-
tion between the Watson-sphere and potential-shift approaches to including boundary conditions in cluster cal-
culations of perfect and defect structures of ionic crystals by the self-consistent-field scattered-wave X method.
