Nuclear orientation of thermally prepared^114mInCu by the brute-force method

Abstract

We report the results of brute-force orientation experiments on several alloys of^114mInCu prepared by different thermal methods, with the goal of clarifying the origins of the deviations from the theoretical nuclear orientation effect reported by several groups for this system. In particular, using thin diffused samples we obtain essentially the same attenuation as previously reported for both^114mIn and¹¹¹In implanted into Cu crystals and foils. Thicker diffused or melted samples show less or more attenuation, respectively. We find no evidence for thermal gradients between samples and thermometers as a cause for the observed deviations.
