Measurement of the Proton Asymmetry Parameter C in Neutron Beta Decay
M. Schumann, M. Kreuz, M. Deissenroth +7
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 pres…
GRANIT project: a trap for gravitational quantum states of UCN
G. Pignol, K. V. Protasov, D. Rebreyend +22
Previous studies of gravitationally bound states of ultracold neutrons showed the quantization of energy levels, and confirmed quantum mechanical predictions for the average size o…
Unrecognized Backscattering in Low Energy Beta Spectroscopy
M. Schumann, H. Abele
We present studies on electron backscattering from the surface of plastic scintillator beta detectors. By using a setup of two detectors coaxial with a strong external magnetic fie…
Measurement of the Neutrino Asymmetry Parameter B in Neutron Decay
M. Schumann, T. Soldner, M. Deissenroth +7
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=0.980…
Analytically derived limits on short-range fifth forces from quantum states of neutrons in the Earth's gravitational field
Alexander Westphal, Hartmut Abele, Stefan Baessler
Recently, quantum states of ultra-cold neutrons in the Earth's gravitational field have been observed for the first time. From the fact that they are consistent with Newtonian grav…
Neutron beta-decay and the quark-mixing CKM-matrix
Hartmut Abele
Neutrons study a number of hot topics from the field of particle physics and cosmology: Recent measurements of various mixed American-British-French-German-Hungarian-Japan-Russian…
