Neutron-Neutron Scattering Length

Physical Review, 1961
The final-state interaction of the two neutrons from the reaction pi / sup -/ + d yields 2n + gamma has a pronounced and distinctive effect on tbe momentum spectrum of the outgoing particles. In particular, the neutron spectrum is sharply peaked in the neighborhood of 2 Mev, with a shape that is quite sensitive to the strength of the nn interaction. In

Direct Measurement of Neutron-Neutron Scattering

AIP Conference Proceedings, 2003
In order to resolve long‐standing discrepancies in indirect measurements of the neutron‐neutron scattering length ann and contribute to solving the problem of the charge symmetry of the nuclear force, the collaboration DIANNA (Direct Investigation of ann Association) plans to measure the neutron‐neutron scattering cross section σnn.

Charge asymmetry and neutron-neutron scattering

Nuclear Physics A, 1975
Abstract The uncertainty in the subtraction of electromagnetic effects from S-wave proton-proton scattering potentials is studied in two models using unitarily transformed potentials. Restrictions on these models caused by theoretical, off-shell and deuteron constraints are imposed.

Inelastic Neutron Scattering With Fission Neutrons

Canadian Journal of Physics, 1971
A detailed investigation has been conducted of the usefulness of fission-spectrum neutrons for inelastic neutron scattering studies. A Ge(Li)–NaI(Tl) annular pair spectrometer was employed in conjunction with a versatile in-core irradiation facility to conduct this evaluation.

Neutron Scattering

2017
Neutron scattering is one of the most powerful and versatile experimental technique used to investigate the structure and dynamics of condensed matter at the atomic scale up to the hundreds of nanometers, complementary to other structural probes, such as those using photons (from visible light to synchrotron X-rays) or electrons (microscopy and ...

Neutron Scattering

2012
Small-angle neutron scattering (SANS) and neutron spin echo (NSE) spectroscopy are the two most important neutron scattering methods for the investigation of bulk polymers. They allow analyzing molecular structure as well as motions and make use of H/D-contrast variation.

Applications of Neutron Scattering to Catalysis

1994
With the construction of intense neutron sources, such as at the Institut Laue-Langevin in Grenoble, the number of studies of condensed matter with neutron scattering has increased tremendously. The range of applications includes crystal and magnetic structures, molecular dynamics, disordered materials, polymers, structural excitations, and biology.

Scattering neutrons asymmetrically

Science, 2014
Superconductivity The crystal structure of solid materials often influences their properties. The more symmetric the structure, the less dependent these properties are on the spatial direction.
