Following the theoretical approach of Bansigir & Iyengar [Acta Cryst. (1961), 14, 670-674], an expression for P11 - P12 is developed for a mixed crystal of KC1-KBr with equimolar concentration. It was assumed that among the six nearest neighbours of the K+ ion, three are Cl- and the other three Br-, and that each K+ is accompanied by Cl- and Br- on either side in all three principal directions. The expression P11 - P12 is used to evaluate the polarizabilities, reversal wavelength, ratio and absolute values of strain-optical constants P11 and P12.
