This paper reports on the improved Mainz experiment on tritium $\beta$ spectroscopy which
yields a 10 times higher signal to background ratio than before. The main experimental …

We report on the neutrino mass measurement result from the first four-week science run of
the Karlsruhe Tritium Neutrino experiment KATRIN in spring 2019. Beta-decay electrons from …

We have built an electrostatic electron spectrometer combining both high resolution and
large luminosity. The instrument consists essentially of two superconducting solenoids …

The following quantities have been determined by optical pumping with the spectral line 2537
A ̊ : 183 Hg : I = 1 2 , μ I = 0.513(9) nm , isotopic shift ( 183 Hg − 204 Hg ) = 18.9(8) GHz ; …

The purpose of this study was to determine the incidence of central vein stenosis and occlusion
following upper extremity placement of peripherally inserted central venous catheters (…

Pressures were measured in the graft and the central vein during 104 consecutive angiographic
examinations of failing hemodialysis grafts. Stenosis severity greater than 40% led to a …

The endpoint region of the β-spectrum of tritium was remeasured by an electrostatic
spectrometer with magnetic guiding field. It enabled the search for a rest mass of the electron-…

The Mainz neutrino-mass experiment investigates the endpoint region of the tritium β-decay
spectrum with a MAC-E spectrometer to determine the mass of the electron antineutrino. By …

Objective: To assess the utility of full bowel preparation with oral nonabsorbable antibiotics
in preventing infectious complications after elective colectomy. Background: Bowel …
