Inhomogeneous nucleosynthesis with neutron diffusion
Physical Review D, 1988It was recently proposed that a critical, i.e., closure, baryon density could be compatible with helium and deuterium observations, if this baryon density were suitably inhomogeneous during cosmic nucleosynthesis. In this scenario, neutrons would diffuse out of the high-density regions, which would lead to a nonstandard nucleosynthesis, with reduced ...

The diffusion coefficient of thermal neutrons
Il Nuovo Cimento, 1958Diffusion of slow, neutrons in an extended uniform medium is treated by a method which accounts for the thermal motion of the medium. If neutron capture is absent, a single integral equation has to be solved, in order to determine the velocity distribution and the diffusion coefficient. A system of such equations is obtained for a capturing medium. For

Abstract The effect of non-uniform temperature upon stationary distributions of thermal neutrons in extended non-absorbing media is studied on the basis of transport theory. Expressions are given by which the thermal diffusion factor, along with the coefficient of ordinary diffusion, can be computed for any given scattering law.

Some Topics in Neutron Diffusion Theory
Reports on Progress in Physics, 1956This paper is divided into four sections. In the first section the integro-differential neutron transport equation is given in its most general form. The form of the scattering law for elastic collisions with moderating nuclei, at rest or in motion, is discussed.

Diffuse neutron scattering of PdMn
Journal of Physics F: Metal Physics, 1975The giant moment in a dilute PdMn (0.23 at% ) alloy has been investigated in the paramagnetic phase at a temperature of 1.4k by means of diffuse neutron scattering. A very high peak in the forward direction was observed, corresponding to a total moment which is much larger than that obtained from magnetization measurements.

The thermalization and diffusion of neutrons in polyphenyls
Journal of Nuclear Energy, 1969Abstract The thermal neutron diffusion length in Dowtherm-A has been measured at 20°, 50°, 80°, 110°, 140°, 170°, 200° and 220°C. By varying the neutron absorption cross-section by the addition of an organic boron compound the neutron diffusion constant and diffusion heating constant were determined at 20°, 80°, 140° and 200°C.
