An improved upper limit on the neutrino mass from a direct kinematic method by KATRIN
M. Aker, K. Altenmüller, M. Arenz +205
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…
Ultra-stable implanted 83Rb/83mKr electron sources for the energy scale monitoring in the KATRIN experiment
M. Zbořil, S. Bauer, M. Beck +13
The KATRIN experiment aims at the direct model-independent determination of the average electron neutrino mass via the measurement of the endpoint region of the tritium beta decay…
Limits on the release of Rb isotopes from a zeolite based 83mKr calibration source for the XENON project
V. Hannen, E. Aprile, F. Arneodo +12
The isomer 83mKr with its half-life of 1.83 h is an ideal calibration source for a liquid noble gas dark matter experiment like the XENON project. However, the risk of contaminatio…
Feasibility of photoelectron sources for testing the energy scale stablity of the KATRIN beta-ray spectrometer
O. Dragoun, A. Spalek, J. Kaspar +5
Photoabsorption of nuclear gamma-rays in thin metallic convertors was examined with the aim to produce monoenergetic photoelectrons of kinetic energy around 18.6 keV and natural wi…
Long term stability of the energy of conversion electrons emitted from solid 83Rb/83mKr source
D. Venos, J. Kaspar, M. Zboril +8
The mono-energetic conversion electrons from the decay of 83mKr represent a unique tool for the energy calibration, energy scale monitoring and systematic studies of the tritium be…
Internal conversion coefficients for superheavy elements
O. Dragoun, M. Rysavy, A. Spalek
The internal conversion coefficients (ICC) were calculated for all atomic subshells of the elements with 104<=Z<=126, the E1...E4, M1...M4 multipolarities and the transition energi…
A possible origin of the endpoint anomaly in tritium beta-spectrum
J. Rizek, V. Brabec, O. Dragoun +2
The influence of the residual T atoms appearing after the decay of T_2 molecule on the beta-spectrum shape is considered. Recent experiments performed in Mainz, Troitsk, and Liverm…
