Comparison of ultracold neutron sources for fundamental physics measurements
G. Bison, M. Daum, K. Kirch +20
Ultracold neutrons (UCNs) are key for precision studies of fundamental parameters of the neutron and in searches for new CP violating processes or exotic interactions beyond the St…
Detection system for forward emitted photons at the Experimental Storage Ring at GSI
V. Hannen, D. Anielski, C. Geppert +10
A single photon counting system has been developed for efficient detection of forward emitted fluorescence photons at the Experimental Storage Ring (ESR) at GSI. The system employs…
Low-energy Calibration of XENON1T with an Internal Ar Source
E. Aprile, K. Abe, F. Agostini +161
A low-energy electronic recoil calibration of XENON1T, a dual-phase xenon time projection chamber, with an internal Ar source was performed. This calibration source features…
Direct demonstration of the two-phonon structure of the state of Sr
J. Isaak, D. Savran, N. Pietralla +7
We have studied the decay pattern of the state of Sr to probe its quadrupole-octupole coupled two-phonon structure. In particular, a uniqu…
Modern Ives-Stilwell Experiments At Storage Rings: Large Boosts Meet High Precision
G. Gwinner, B. Botermann, C. Geppert +14
We give a brief overview of time dilation tests using high-resolution laser spectroscopy at heavy-ion storage rings. We reflect on the various methods used to eliminate the first-o…
Comment on "Missing Transverse-Doppler Effect in Time-Dilation Experiments with High-Speed Ions"
G. Saathoff, S. Reinhardt, R. Holzwarth +14
In an article "Missing Transverse-Doppler Effect in Time-Dilation Experiments with High-Speed Ions" by S. Devasia [arXiv:1003.2970v1], our recent Doppler shift experiments on fast…
Ta(n,) cross-section measurement and the astrophysical origin of Ta isotope
R. Garg, S. Dellmann, C. Lederer-Woods +11
Tantalum-180m is nature's rarest (quasi) stable isotope and its astrophysical origin is an open question. A possible production site of this isotope is the slow neutron capture pro…
TRIGA-SPEC: A setup for mass spectrometry and laser spectroscopy at the research reactor TRIGA Mainz
J. Ketelaer, J. Krämer, D. Beck +17
The research reactor TRIGA Mainz is an ideal facility to provide neutron-rich nuclides with production rates sufficiently large for mass spectrometric and laser spectroscopic studi…
