Effects of temperature on the structure of neutron stars at high temperature
General Relativity and Gravitation, 2017In Newtonian physics, higher temperature leads to higher thermal pressure, which provides stronger support against the gravitational contraction of stars. However, in the temperature range of tens of MeV involved in the evolution of a proto-neutron star or a higher massive neutron star, the effects of temperature are richer.

A low-temperature Weissenberg camera for neutrons
Journal of Applied Crystallography, 1981The construction and performance of a neutron Weissenberg camera for temperatures down to 4 K is described. Exposure times are similar to the X-ray case. The background from the cryostat walls can be eliminated. Examples of applications in the fields of magnetic structures which are incommensurate with their chemical unit cells, crystallographic phase ...

Low temperature neutron irradiation of niobium
Scripta Metallurgica, 1976A study was made to determine the effect of low temperature neutron irradiation and post-irradiation annealing on the yield stress of low and intermediate oxygen content niobium. The results are compared with previous results to determine the type of neutron-produced defect that causes the changes in the yield stress. 12 references. (JFP)

Neutron Capture Data at Stellar Temperatures
Reviews of Modern Physics, 1965Neutron capture cross sections are averaged over Maxwell-Boltzmann neutron distributions for temperatures pertinent to slow nucleosynthesis ($s$ process) in red giant stars. Such cross sections, together with isotopic abundances, provide the major quantitative experimental tests of the theory.

Temperature measurement by neutron resonance radiography
Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment, 1989Abstract We present a new method of data analysis for determination of temperature from the Doppler broadening of neutron resonance absorption cross sections. The method is model independent and simple to use. It has been applied to measurements on samples of rhenium and tantalum and has given temperatures to an accuracy better than ±1°C.

Influence of Temperature on the Groups of Slow Neutrons
Nature, 1936WE have investigated the influence of temperature on the activation of silver by slow neutrons, separating the effects due to the groups A, B and C as defined by Amaldi and Fermi1. The arrangement used is shown in plan in Fig. 1. Absorbers of cadmium (0.258 gm./cm.2) and silver (0.077 gm./cm.2) were employed to separate the groups, and the use of a ...
