Progress report uranium samples

233U samples are required by UHEI for gamma-spectroscopy (task 1.1), by LMU as ion-beam source (task 1.2), by TU WIEN for crystal doping (task 1.4), and potentially JYU as collision target. The chemical procedures developed to produce the required samples will be decribed in a report, along with quantitative measurements of radioactivity, purity, and other relevant parameters.
