Opis:: Positron annihilation characteristics as a function of composition and annealing in zinc vapour were measured and compared with photoluminescence spectra for Zn$\text{}_{1-x}$Mg$\text{}_{x}$Se mixed crystals with 0 ≤ x ≤ 0.6. The positron annihilation data show that there is a substantial number of divacancies present in the system under study. The concentration of such defects is reduced at least by the factor of two upon annealing in zinc vapour.

Opis:: The first experimental study of the Compton profiles of Zn$\text{}_{1-x}$Mg$\text{}_{x}$Se for x=0.25, 0.47, 0.56 mixed crystals is presented. The Compton profiles were measured with the use of the $\text{}^{241}$Am radioactive source with a resolution of 0.57 a.u. The experimentally obtained Compton profiles were compared with the theoretical ones based on the free-atom model. The results are interpreted in terms of outermost electrons of Zn and Mg being promoted to the higher momentum states, and 4p-electrons of Se becoming more delocalised in a solid, being thus promoted to the lower momentum states.
