Improved limit on the effective electron neutrino mass with the ECHo-1k experiment
Fabienne Adam, Felix Ahrens, Luis E. Ardila Perez +56
The effective electron neutrino mass can be determined by analyzing the endpoint region of the Ho electron capture spectrum, provided a measurement with high energy resolut…
Penning-trap measurement of the -value of the electron capture in for the determination of the electron neutrino mass
Christoph Schweiger, Martin Braß, Vincent Debierre +19
The investigation of the absolute scale of the effective neutrino mass remains challenging due to the exclusively weak interaction of neutrinos with all known particles in the stan…
Non-Lorentzian atomic natural line-shape of core level multiplets: Access high energy x-ray photons in electron capture nuclear decay
Marc Merstorf, Martin Braß, Maurits W. Haverkort
We present a method to calculate the natural line width and energy dependent line shape due to fluorescence decay of core excited atoms within a full relativistic multi-reference c…
Detection of metastable electronic states by Penning trap mass spectrometry
Rima Xenia Schüssler, Hendrik Bekker, Martin Braß +19
State-of-the-art optical clocks achieve fractional precisions of and below using ensembles of atoms in optical lattices or individual ions in radio-frequency traps. Prom…
Ab initio calculation of the electron capture spectrum of 163Ho: Auger-Meitner decay into continuum states
M. Brass, M. W. Haverkort
Determining the electron neutrino mass by electron capture in Ho relies on an accurate understanding of the differential electron capture nuclear decay rate as a function o…
calculation of the calorimetric electron capture spectrum of Holmium: Intra-atomic decay into bound-states
M. Braß, C. Enss, L. Gastaldo +1
The determination of the electron neutrino mass by electron capture in Ho relies on a precise understanding of the deexcitation of a core hole after an electron capture eve…
