The angle correlations of annihilation radiation (ACAR) in TiMe shape memory intermetallic compounds (where Me stands for Fe, Co, Ni, Pd, Pt, and Au) were investigated. It was established that in the sequence of compounds studied, the ACAR gradually changes from the average of the correlations corresponding to the two pure components toward those close to the pure Ti. Consideration of the conduction electrons as free electron gas allowed us to determine the valence band widths and the numbers of sp electrons. Using positron annihilation we also obtained information concerning the B2 phase stability in the studied compounds.
