Kreuz, M., Nesvizhevsky, V. V., Schmidt-Wellenburg, P., Soldner, T., Thomas, M., Boerner, H. G., ...
We present a method to measure the resonance transitions between the gravitationally bound quantum states of neutrons in the GRANIT spectrometer. The purpose of GRANIT is to improve the accuracy of...
Ultracold-neutron infrastructure for the gravitational spectrometer GRANIT (2008)
Schmidt-Wellenburg, P., Andersen, K. H., Courtois, P., Kreuz, M., Mironov, S., Nesvizhevsky, V. V., ...
The gravitational spectrometer GRANIT will be set up at the Institut Laue Langevin. It will profit from the high ultracold neutron density produced by a dedicated source. A monochromator made of...
Measurement of the Proton Asymmetry Parameter C in Neutron Beta Decay (2007)
Schumann, M., Kreuz, M., Deissenroth, M., Glueck, F., Krempel, J., Maerkisch, B., ...
The proton asymmetry parameter C in neutron decay describes the correlation between neutron spin and proton momentum. In this Letter, the first measurement of this quantity is presented. The result...
GRANIT project: a trap for gravitational quantum states of UCN (2007)
Pignol, G., Protasov, K. V., Rebreyend, D., Vezzu, F., Nesvizhevsky, V. V., Petukhov, A. K., ...
Previous studies of gravitationally bound states of ultracold neutrons showed the quantization of energy levels, and confirmed quantum mechanical predictions for the average size of the two lowest...
Measurement of the Neutrino Asymmetry Parameter B in Neutron Decay (2007)
Schumann, M., Soldner, T., Deissenroth, M., Glueck, F., Krempel, J., Kreuz, M., ...
A new measurement of the neutrino asymmetry parameter B in neutron decay, the angular correlation between neutron spin and anti-neutrino momentum, is presented. The result, B=0.9802(50), agrees with...
Characterization of a ballistic supermirror neutron guide (2005)
Abele, H., Dubbers, D., Haese, H., Klein, M., Knoepfler, A., Kreuz, M., ...
We describe the beam characteristics of the first ballistic supermirror neutron guide H113 that feeds the neutron user facility for particle physics PF1B of the Institute Laue-Langevin, Grenoble...
