“…Previous Xray dieaction measurements clearly indicate the presence of precipitates of Ni5Zr in the Ni(Zr) samples and TEM show equilateral triangle shaped (0.1 Fm on side) semi-coherent inclusions 181. A e+ work hnction, estimated to be significantly greater in Ni than in the Ni5Zr phase, indicates that e+ may be trapped in the precipitates [7]. The possibility also exists that a substantial fraction of e+ annihilate at precipitate-bulk interfaces.…”

“…Homogeneous solid solutions of Cuwn), not considered by Doyarna, as well as Cu(Ni) were prepared in an attempt to reproduce the above results using our DB system (for experimental details see [7]). The form of DB spectra are characterized by the lineshape parameters S and W, being the integral of counts over regions near the peak and in the wings respectively.…”

scite is a Brooklyn-based organization that helps researchers better discover and understand research articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by students and researchers from around the world and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
