We discuss the use of the positron annihilation method to study the electron structure of alkali halide monocrystals, particularly the electron density and the effective charge of the ions. The distribution of electron density and the values of the effective ion charge are found experimentally for two crystallographic directions, 〈110〉 and 〈100〉, in a KBr monocrystal. On the basis of the data obtained it is concluded that this is an effective method for obtaining information about the anisotropy of electron states in the crystal.
