Abstract

The neutrino mass can be extracted from a high statistics, high resolution calorimetric spectrum of electron capture in $${}^{163}$$ 163 Ho. In order to better understand the shape of the calorimetric electron capture spectrum, a second isotope was measured with a close to ideal absorber-source configuration. $${}^{193}$$ 193 Pt was created by irradiating a $${}^{192}$$ 192 Pt-enriched platinum foil in a nuclear reactor. This Pt-in-Pt absorber was designed to have a nearly ideal absorber-source configuration. The measured $${}^{193}$$ 193 Pt calorimetric electron capture spectrum provides an independent check on the corresponding theoretical calculations, which have thus far been compared only for $${}^{163}$$ 163 Ho. The first experimental and theoretically calculated spectra from this $${}^{193}$$ 193 Pt-in-Pt absorber are presented and overlaid for preliminary comparison of theory with experiment.
