Possible multi-orbital ground state in CeCuSi
Andrea Amorese, Andrea Marino, Martin Sundermann +16
The crystal-field ground state wave function of CeCuSi has been investigated with linear polarized -edge x-ray absorption spectroscopy from 250mK to 250K, thus covering…
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…
Dual nature of 5 electrons in the isostructural UMSi family: from antiferro- to Pauli paramagnetism via hidden order
Andrea Amorese, Martin Sundermann, Brett Leedahl +16
Using inelastic x-ray scattering beyond the dipole limit and hard x-ray photoelectron spectroscopy we establish the dual nature of the U electrons in UMSi (M = Pd, Ni,…
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…
