Nonlinear calcium King plot constrains new bosons and nuclear properties
A. Wilzewski, L. I. Huber, M. Door +39
Nonlinearities in King plots (KP) of isotope shifts (IS) can reveal the existence of beyond-Standard-Model (BSM) interactions that couple electrons and neutrons. However, it is cru…
High-precision determination of factors and masses of and
F. HeiÃe, M. Door, T. Sailer +13
We present the measurements of individual bound electron factors of and on the relative level of per billion. Th…
$\text{Direct}~Q\text{-Value Determination of the}~β^-~\text{Decay of} ~^{187}\text{Re}$
P. Filianin, C. Lyu, M. Door +15
The cyclotron frequency ratio of to ions was measured with the Penning-trap mass spectrometer PENTATRAP. The achieved result of…
Direct determination of the excitation energy of quasi-stable isomer Ta
D. A. Nesterenko, K. Blaum, P. Delahaye +11
Ta is a naturally abundant quasi-stable nuclide and the longest-lived nuclear isomer known to date. It is of interest for, among others, the search for dark matter, for th…
Mass-difference measurements on heavy nuclides with at an eV/c2 accuracy level with PENTATRAP
A. Rischka, H. Cakir, M. Door +13
First ever measurements of the ratios of free cyclotron frequencies of heavy highly charged ions with Z>50 with relative uncertainties close to 1e-11 are presented. Such accurate m…
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…
