Micromegas neutron beam monitor neutronics
Radiation Protection Dosimetry, 2005The Micromegas is a type of ionising radiation detector that consists of a gas chamber sandwiched between two parallel plate electrodes, with the gas chamber divided by a Frisch grid into drift and amplification gaps. Investigators have applied it to a number of different applications, such as charged particle, X-ray and neutron detection. A Micromegas

Neutron halo structure, 9Li-neutron and neutron-neutron momentum correlations in 11Li
Nuclear Physics A, 1992Abstract The approximate three-body approach COSMA is used to explore the structure of 11Li. This “Borromean” system is discussed with reference to the similar system 6He for which information on the binary subsystems is more complete. Spatial densities and a variety of correlated momentum distributions for 9Li-n and nn are calculated.

Calculations of neutron spectra after neutron–neutron scattering
Journal of Physics G: Nuclear and Particle Physics, 2004A direct neutron–neutron scattering length, ann, measurement with the goal of 3% accuracy (0.5 fm) is under preparation at the aperiodic pulsed reactor YAGUAR. A direct measurement of ann will not only help resolve conflicting results of ann by indirect means, but also in comparison to the proton–proton scattering length, app, shed light on the charge ...

Abstract The experimental determination of the neutron-neutron scattering length is of interest from the point of view of both the study of nucleon-nucleon interactions and the verification of the hypothesis of isotopic invariance of strong interactions at low energies.

NEUTRON LOGGING OF DRILL HOLES: THE NEUTRON‐NEUTRON METHOD
GEOPHYSICS, 1951Experiments were performed to determine the distribution of thermal neutrons and of indium resonance neutrons in continuous hydrogenous media and in pipes passing through hydrogenous media. Included in the study were water, brine, mixtures of sand and water, and mixtures of sand and brine. Experiments in a continuous typical barite drilling mud showed

Physics World, 1996
Neutrons make up more than half the matter in our everyday world. As its name implies, the neutron is electrically neutral, but the quarks that make up a neutron are charged. Moreover, the distributions of positive and negative quarks inside a neutron are different, which leads to a separation of charge inside the uncharged particle.

Reviews of Modern Physics, 1967
The present status of the problem of charge dependence is discussed. The information about the neutron-neutron interaction derived from the two-neutron system, three-nucleon systems, final-state interactions in multiparticle reactions, and peripheral processes is critically evaluated.

Neutron Spin-Neutron Orbit Interaction with Slow Neutrons
Physical Review Letters, 1963Measurements were made of the polarization ratio of the scattered intensities for the two neutron spin states for two reflections (110) and (220) for positive angles and for the reflection (110) at negative angles. Very high neutron polarization was available and the intensity was studied as the magnetic field on the crystal was reduced to zero so as ...

About neutrons, neutron metrology and neutron spectrometry
Delivered as part of the Soil Moisture Training on 22 January 2025. The project (21GRD08 SoMMet) has received funding from the European Partnership on Metrology, co-financed from the European Union’s Horizon Europe Research and Innovation Programme and by the Participating States.openaire +1 more source
International Journal of Radiation Oncology*Biology*Physics, 1982
Abstract Tumor responses depend on a number of factors, of which the intrinsic radiosensitivity of the cells and their oxygenation condition can be considered as most important. Variations of the sensitivity in the cell cycle and differences between resting and proliferating cells are considered to play a smaller part.
