Doppler broadening method of positron annihilation (DOBPA method) isdeveloped, and applied to the study of electronic structures of alkali halides.Radiation from positron annihilation in 14 kinds of alkali halide single crystalswere measured with a Ge(Li) detector system. Observed Doppler broadenedspectra were unfolded by computer, and intrinsic distributions were obtained.Electron momentum distributions were extracted from these distributions. Tostudy anisotropy of the momentum distribution, radiation was measured along the[1104 direction as well as along the [1004 direction. Anisotropy of the momentumdistribution was observed except for lithium halides and cesium halides. Thestrongest anisotropy was found in RbBr.
