Neutron scattering and extra short range interactions
V. V. Nesvizhevsky, G. Pignol, K. V. Protasov
The available data on neutron scattering were analyzed to constrain a hypothetical new short-range interaction. We show that these constraints are several orders of magnitude bette…
Measurement of the parity-violating triton emission asymmetry in the reaction 6Li(n,alfa)3H with polarised cold neutrons
V. A. Vesna, Yu. M. Gledenov, V. V. Nesvizhevsky +5
We describe measurements of the parity-violating (P-odd) triton emission asymmetry coefficient in the 6Li(n,alfa)3H reaction with polarised cold neutrons. Experiments were carried…
A source of ultra-cold neutrons for the gravitational spectrometer GRANIT
P. Schmidt-Wellenburg, P. Geltenbort, V. V. Nesvizhevsky +4
We present the status of the development of a dedicated high density ultra-cold neutron (UCN) source dedicated to the gravitational spectrometer GRANIT. The source employs superthe…
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…
Experimental constraints for additional short-range forces from neutron experiments
V. V. Nesvizhevsky, G. Pignol, K. V. Protasov
We present preliminary results on sensitivity of experiments with slow neutrons to constrain additional forces in a wide distance range: from picometers to micrometers. In the sub-…
Efficient extraction of a collimated ultra-cold neutron beam using diffusive channels
P. Schmidt-Wellenburg, J. Barnard, P. Geltenbort +4
We present a first experimental demonstration of a new method to extract a well-collimated beam of ultra-cold neutrons (UCN) from a storage vessel. Neutrons with too large divergen…
