Eventually arrived: The magnet system of PERC was completed and delivered to the MLZ
Its dimensions are impressively large, the particles under investigation with its help however microscopically small. The 12 m long magnet system of PERC for high-precision studies of the neutron beta decay was delivered in September to the FRM II research reactor – now this event was presented in a slide show and a video.

Obituary for Andrey Nikolaevich Ivanov
We mourn Andrey Nikolaevich Ivanov. Andrey was born on June 3, 1945 in what was then Leningrad. Since 1993 he was a university professor at the Faculty of Physics, named "Peter The Great St. Petersburg Polytechnic University" after Peter the Great. Since 1995 he has been a guest professor at the Institute for Nuclear Physics for several years and has been closely associated with the institute ever since. Mehr
Decoherence-free entropic gravity: Model and experimental tests
Erik Verlinde's theory of entropic gravity [E. Verlinde, J. High Energy Phys. 04 (2011) 029], postulating that gravity is not a fundamental force but rather emerges thermodynamically, has garnered much attention as a possible resolution to the quantum gravity problem Mehr
Tests of Fundamental Quantum Mechanics and Dark Interactions with Low Energy Neutrons--Extended Version
Among the known particles, the neutron takes a special position, as it provides experimental access to all four fundamental forces and a wide range of hypothetical interactions. Mehr
Neutron Radiography and Tomography of the Drying Process of Screed Samples
The moisture content of screed samples is an essential parameter in the construction industry, since the screed must dry to a certain level of moisture content to be ready for covering. Mehr
Accurate Measurement of the Beta-Asymmetry in Neutron Decay Rules out Dark Decay Mode
The question of the nature of dark matter is one of the major challenges of elementary particle physics. Mehr
Limit on the Fierz Interference Term b from a Measurement of the Beta Asymmetry in Neutron Decay
In the standard model of particle physics, the weak interaction is described by vector and axial-vector couplings only. Mehr
MONOPOL - A traveling-wave magnetic neutron spin resonator for tailoring polarized neutron beams
We report on first experimental tests of a neutron magnetic spin resonator at a very cold neutron beam port of the high flux reactor at the ILL Grenoble. Mehr
Novel Quantum Effect Found: Spin-Rotation Coupling
It was predicted 30 years ago, now the effect was measured for the first time by scientists at TU Wien (Vienna): The neutron spin exhibits inertial effects. Mehr
Geht das nicht genauer?
Das Motto der Naturwissenschaft: Was man messen kann, messen. Was man nicht messen kann, messbar machen. Und was man schon gemessen hat, noch einmal exakter messen. Mehr
