Positron Annihilation Study of Fe/sub 1-X/-B/sub X/ Crystalline Binary System

摘要

The Fe/sub 1-x/-B/sub x/ system with x=0, 0.025, 0.099, 0.150, 0.185, 0.307, 0.333, 0.500 and 1.00 was studied by measuring positron angular correlation and Doppler broadening of annihilation gamma -line energy. The dependence of the h parameter indicates a tendency for a preferred annihilation of positron at a B atomic site in the concentration range x <= 0.333. The S parameter obtained from the energy distribution of the annihilation line gives the same conclusion as does the dependence of the h parameter. (Atomindex citation 12:600768)
