Neutron temperature measurements with 176Lu

Journal of Nuclear Energy. Part A. Reactor Science, 1959
A relative calibration of the Lu/sup 176/(n, gamma y) reaction is reported. It was found that the Lu/sup 176/(n, gamma ) reaction is potentially capable of measuring neutron temperature in the 0 to 110 deg C range to about 5 deg C. (C.J.G.)

Slowing Down Spectrum and Neutron Temperature in a Thermal Neutron Flux Density Standard

Metrologia, 1966
Epithermal and thermal flux parameters for the thermal flux density standard at the National Research Council have been measured to allow a more accurate calculation of activation rates. The epithermal spectrum is found to follow a E-0.95 law, where E is the neutron energy.

Cooling of Accretion-Heated Neutron Stars

, 2017
We present a brief, observational review about the study of the cooling behaviour of accretion-heated neutron stars and the inferences about the neutron-star crust and core that have been obtained from these studies.

Neutron diffraction at simultaneous high temperatures and pressures, with measurement of temperature by neutron radiography

Mineralogical Magazine, 2001
AbstractThe commissioning and operation of apparatus for neutron diffraction at simultaneous high temperatures and pressures is reported. The basic design is based on the Paris-Edinburgh cell using opposed anvils, with internal heating. Temperature is measured using neutron radiography. The apparatus has been shown in both on-line and off-line tests to

Neutron Diffusion in a Temperature Gradient

Nuclear Science and Engineering, 1962
>The space energy distribution of neutrons diffusing in a source-free, nonabsorbing medium possessing a temperature gradient is obtained by solving the appropriate Boltzmann equation to a second order approximation using the expansion technique of Chipman and Enskog.

Temperature of neutron stars

International Journal of Modern Physics D, 2016
We start with a brief introduction to the historical background in the early pioneering days when the first neutron star thermal evolution calculations predicted the presence of neutron stars hot enough to be observable. We then report on the first detection of neutron star temperatures by ROSAT X-ray satellite, which vindicated the earlier prediction

Neutron Scattering

Modern Condensed Matter Physics, 2019
Several salient features are apparent from this table: – electrons are charged and experience strong, long-range Coulomb interactions in a solid. They therefore typically only penetrate a few atomic layers into the solid. Electron scattering is therefore

Temperature Shift of Neutron Resonances

1986
Temperature-induced shift of neutron resonances have been experimentally observed studying low-energy resonances of 103Rh, 109Ag, l61Dy and l63Dy with a time-of-flight spectrometer at the Dubna pulsed reactor The shifts are regarded as an analogue to the second-order Doppler effect in Mossbauer gamma-ray spectroscopy.
