Radiative neutron capture by deuterium
Physical Review C, 1986The $^{2}$H(n,\ensuremath{\gamma}${)}^{3}$H reaction has been studied with polarized and unpolarized neutrons of energies ranging from 9 to 14 MeV. Angular distributions of cross section were measured at ${E}_{\mathrm{n}}$(lab)=9.0, 10.8, and 14.0 MeV, \ensuremath{\sigma}(90\ifmmode^\circ\else\textdegree\fi{}) was measured at 6.85 MeV, and an analyzing-

Neutron Penetration During Neutron Capture Therapy
Physics in Medicine and Biology, 1962Neutron transport theory has been applied to the problem of penetration of a broad beam of neutrons into finite and semi-infinite volumes of aqueous media. The expressions derived are in excellent agreement with data obtained using a human head phantom of tissue equivalent gel.

Boron Neutron Capture Therapy for Cancer
Scientific American, 1990Boron neutron capture therapy (BNCT) bring together two components that when kept separate have only minor effects on normal cells. The first component is a stable isotope of boron (boron 10) that can be concentrated in tumor cells. The second is a beam of low-energy neutrons that produces short-range radiation when absorbed, or captured, by the boron.

Capture of Neutrons by Atoms in a Crystal
Physical Review, 1939The precise determination of the properties of nuclear resonance levels from the capture of slow neutrons is made difficult by the fact that most of the substances used for absorbers and detectors are in the solid state, so that the calculations of Bethe and Placzek for the influence of the Doppler effect are inapplicable, since these were based on the

Neutron source for Neutron Capture Synovectomy
AIP Conference Proceedings, 2011Monte Carlo calculations were performed to obtain a thermal neutron field from a 239PuBe neutron source inside a cylindrical heterogeneous moderators for Neutron Capture Synovectomy. Studied moderators were light water and heavy water, graphite and heavy water, lucite and polyethylene and heavy water.

Abstract The γ-ray spectrum following slow neutron capture in 238U has been measured as a function of incident neutron energy at the Brookhaven HFBR fast neutron chopper. The decay scheme proposed by previous (d, p) and high resolution thermal (n, γ) measurements has been substantially verified.

At the time of the discovery of the neutron by Chadwick, roentgen rays had been in use in medicine as a diagnostic and therapeutic tool since shortly after their discovery some 37 years previously. Many of the biological effects of ionizing radiations, not only of roentgen rays but also of the radiations from radium and other radioactive elements, were

Neutron capture in perspective
AIP Conference Proceedings, 1991The status of Nuclear Physics is briefly reviewed, and the blanks in our knowledge are highlighted. The nature of the (n,γ) reaction and its contribution to our knowledge of nuclear properties is discussed and a recent study of the 188Os (n,γ)188Os reaction is cited as an example.

Abstract At the Karlsruhe and Tubingen 3.75 MV Van de Graaff accelerators the cross section of the reaction 30Si(n,γ)31Si(2.62 h) was measured by the activation technique via the β spectrum of the 31Si-decay. Natural silicon samples of 50 to 90 μm thickness were irradiated back to back with gold foils which served as capture standard.
