摘要: Angular correlation of two-photon annihilation radiation (ACAR) measurements have been performed to study the effect interstitial impurities (O, C and D) on positronium (Ps) formation in irradiation-induced voids vanadium. It has observed that Ps is sensitively affected by doping with impurities, irradiation dose, temperature, also post-irradiation annealing. The component intensity found be related segregation provides a new experimental method void surfaces.
