The Scattering of Thermal Neutrons by Deuterons

Physical Review, 1940
The cross section for the scattering of very slow neutrons by deuterons is calculated by numerical methods. Polarization is completely neglected and the wave equation for the process is set up in such a form as to take correctly into account exchange effects between the incident neutron and the neutron initially in the deuteron.

Thermal neutron capture in silicon

Physical Review C, 1990
The prompt gamma-rays from thermal nuteron capture in {sup 28,29,30}Si have been studied and the radiative capture cross sections determined as 207{plus minus}4, 120{plus minus}3 and 107{plus minus}2 mb, respectively. There has been a marked increase in the number of transitions observed in {sup 29}Si and a complete decay scheme for this nucleus is ...

Shielding for thermal neutrons

Medical Physics, 1997
The problem of calculating the neutron capture γ‐ray dose rate due to thermal neutron capture in a boron or cadmium rectangular shield is considered. An example is given for shielding for a door at the exit of medical accelerator room maze in order to determine the optimum location of lead relative to the borated polyethylene.

Pulsed thermal neutron source at the fast neutron generator

Applied Radiation and Isotopes, 2009
A small pulsed thermal neutron source has been designed based on results of the MCNP simulations of the thermalization of 14 MeV neutrons in a cluster-moderator which consists of small moderating cells decoupled by an absorber. Optimum dimensions of the single cell and of the whole cluster have been selected, considering the thermal neutron intensity ...

Thermalization of Neutrons

1964
Our first discussion of thermal neutron fields in Sec. 5.3 was based on the idealizing assumption that the neutrons were in a true state of thermal equilibrium and thus had a Maxwellian energy distribution with the temperature of the medium. For reasons already mentioned there, the assumption of such an equilibrium state cannot be rigorously true.

Thermal neutron standards

Metrologia, 2011
Over the 50-year history of Section III (Neutron Measurements) of the Consultative Committee for Ionizing Radiation of the International Committee for Weights and Measures, only a single interlaboratory comparison of thermal neutron measurements has been completed, although a new comparison of this kind is in progress at the time of this writing.
