Laser Spectroscopy of Thulium Isotopes Near the Shell Closure: Nuclear Moment and Charge Radius of
Jana Weyrich, Kenneth van Beek, Harshithbabu +34
We report on resonance ionization laser spectroscopy measurements performed on both neutron-deficient and neutron-rich thulium () isotopes. Isotope shifts were d…
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…
Metallic magnetic calorimeter arrays for the first phase of the ECHo experiment
F. Mantegazzini, A. Barth, H. Dorrer +12
The ECHo experiment has been designed for the determination of the effective electron neutrino mass by means of the analysis of the end-point region of the Ho-163 electron capture…
Detection of missing low-lying atomic states in actinium
Ke Zhang, Dominik Studer, Felix Weber +10
Two lowest-energy odd-parity atomic levels of actinium, 7s^27p 2P^o_1/2, 7s^27p 2P^o_3/2, were observed via two-step resonant laser-ionization spectroscopy and their respective ene…
Specific Heat of Holmium in Gold and Silver at Low Temperatures
Matthew Herbst, Andreas Reifenberger, Clemens Velte +10
The specific heat of dilute alloys of holmium in gold and in silver plays a major role in the optimization of low temperature microcalorimeters with enclosed , s…
Development of a recoil ion source providing slow Th ions including Th in a broad charge state distribution
Raphael Haas, Tom Kieck, Dmitry Budker +7
Ions of the isomer Th are a topic of high interest for the construction of a "nuclear clock" and in the field of fundamental physics for testing symmetries of nature. They…
Highly efficient isotope separation and ion implantation of Ho for the ECHo project
Tom Kieck, Holger Dorrer, Christoph E. Düllmann +3
The effective electron neutrino mass measurement at the ECHo experiment requires high purity Ho, which is ion implanted into detector absorbers. To meet the project specifi…
Optimization of a laser ion source for Ho isotope separation
Tom Kieck, Sebastian Biebricher, Christoph E. Düllmann +1
To measure the mass of the electron neutrino, the "Electron Capture in Holmium-163" (ECHo) collaboration aims at calorimetrically measuring the spectrum following electron capture…
A White Paper on keV Sterile Neutrino Dark Matter
R. Adhikari, M. Agostini, N. Anh Ky +133
We present a comprehensive review of keV-scale sterile neutrino Dark Matter, collecting views and insights from all disciplines involved - cosmology, astrophysics, nuclear, and par…
