Neutrons for rafts, rafts for neutrons

The European Physical Journal E, 2013
The determination of the structure of membrane rafts is a challenging issue in biology. The selection of membrane components both in the longitudinal and transverse directions plays a major role as it determines the creation of stable or tunable platforms that host interactions with components of the outer environment.

Neutron-Proton and Neutron-Neutron Scattering at High Energies

Physical Review, 1949
The phase method and the Born approximation is used to calculate the cross sections of high energy neutrons scattered by protons and neutrons. Various exchange theories are considered for both, central and tensor forces of rectangular and Yukawa well shape.

Neutron Production, Neutron Facilities and Neutron Instrumentation

Reviews in Mineralogy and Geochemistry, 2006
The main natural source of free neutrons is secondary radiation from cosmic radiation (creation of particles by interactions of cosmic radiation particles with atoms of the earth’s atmosphere). The main sources of neutrons generated artificially are nuclear reactors. Free neutrons have an average lifetime of about 888 seconds (e.g., Mampe et al.

Neutron detection and neutron dosimetry

Radiation Protection Dosimetry, 2004
A review is presented on the research and development of inorganic scintillators for position-sensitive thermal neutron detectors to be used at new spallation neutron sources. Furthermore some recent developments in the field of fast-neutron dosimetry will be discussed.

Micromegas neutron beam monitor neutronics

Radiation Protection Dosimetry, 2005
The 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-Neutron Scattering

1992
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 halo structure, 9Li-neutron and neutron-neutron momentum correlations in 11Li

Nuclear Physics A, 1992
Abstract 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, 2004
A 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 ...

Neutron logging of drill holes; the neutron-neutron method

Geophysics, 1951
Abstract Experiments 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.

Neutron-Neutron Interaction

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.
