TLDR
In this article, the elastische Streuung von Neutronenstrahlen with bekannter polarisation wird an 3He bei Einschusenergien von 1,67, 2,43, 3,0, 3 4,4 and 7,8 MeV, measured at seven angles from 25° to 155° using a high pressure gas scintillation counter.Abstract:
Elastic scattering by 3He for 1.67, 2.43, 3.0, 3.4 and 7.8 MeV neutron beams of known polarization was measured at seven angles from 25° to 155° using a high pressure gas scintillation counter. The geometrical and multiple scattering effects were accounted for by the Monte Carlo technique. The corrected results were compared with previous experimental data and with the existing predictions based on microscopic calculations and phenomenological analyses.
Elastische Streuung polarisierter niedrigenergetischer Neutronen an 3He
Die elastische Streuung von Neutronenstrahlen mit bekannter Polarisation wird an 3He bei Einschusenergien von 1,67, 2,43, 3,0, 3,4 und 7,8 MeV und Einschuswinkeln von 25° bis 155° mittels eines Hochdruck-Gas-Scintillatorzahlers untersucht.
Die Effekte der geometrischen und Vielfachstreuungen werden mittels Monte-Carlo-Methoden berucksichtigt.
Die korrigierten Resultate werden mit fruheren experimentellen Daten und mit Ergebnissen verglichen, die auf mikroskopischen Rechnungen und phanomenologischen Theorien beruhen.read more

TL;DR: In this article, measurements of the analyzing power of elastic n-3 He scattering in the energy range from 3.7 to 22 MeV are reported, which is not in agreement with a previous experiment which caused problems in phase shift analyses.

Analyzing power of n-3He elastic scattering from 1 to 2 MeV
TL;DR: In this paper, measurements of the analyzing power of the elastic n-3 He scattering in the energy range from 0.95 to 2.0 MeV are reported, showing the importance of Coulomb effects at these low energies and of the isospin structure of the A = 4 system.

TL;DR: The recent appearance of high-intensity polarized beams with a small energy spread has made feasible a number of experiments which could not have been considered just a few years ago as discussed by the authors, and the volume of experimental data can thus be expected to increase rapidly; the results should be precise and reliable.

Energy levels of light nuclei A = 4
W. E. Meyerhof,T. A. Tombrello +1 more
TL;DR: In this paper, the energy levels for A = 4 nuclei with emphasis on material leading to information about the structure of the A =4 systems were analyzed. But the authors focused on the A -4 nuclei.

4He levels from a charge-independent analysis of 3H(p, n)3He
TL;DR: An R-matrix analysis of the differential cross section and neutron polarization in the reaction 3H(p, n)3He is presented in this article, which can be expected on the basis of shell-model arguments.
