cross sectionsthermal neutronsThis paper summarizes measurements of the thermal neutron absorption cross-section of boron made at Harwell, in Sweden, and in the U.S.A. It also describes a new measurement made at Harwell. The agreement between the Harwell and Swedish values is good, but there ...
The total neutron cross sections of 10B, 11B, C and O and the absorption cross section of 10B have been measured for neutron energies between 10 and 500 keV. The 10B absorption cross section does bot deviate appreciably from a 1/ν dependence in this interval of neutron energies. The ...
In space exploration, neutron absorption has become a significant concern as neutron mostly generated from the interaction of cosmos radiation with matter can cause disastrous malfunction or lethal damage to space equipment and astronauts (Fig.10a). Owing to high neutron absorption cross-section of 383...

The Absorption of Neutrons Detected by Boron and Lithium The neutron-nucleus collision cross sections of various elements have been investigated for neutrons that are detectable by means of (1) the boron and (2) lithium neutron capture reaction and that are strongly absorbed by cadmium. The co....
IN the same arrangement as used for silver absorption, we have measured the influence of temperature on the absorption of neutrons in Fermi's group `C' by boron and cadmium, using the 2.3 min. silver activity as detector.doi:10.1038/138505a0FOMIN, V...
1.Boron 10 has the property of high absorption of thermal neutrons, and its absorption cross section is 3837 targets, which makes it a highly efficient thermal neutron absorber. Boron 10 usually exists in the form of white powdery crystals or scaly shiny crystals. ...
In pressurized water reactors (PWRs), boron-10 (10B) is added to the primary fluid as boric acid to regulate criticality and power distribution within the core. Indeed, 10B possesses a significant neutron absorption cross section of approximately 3845 barns for thermal neutron energy (around 25.3...
Boron neutron capture therapy is about a century old, but still current and active. In this treatment, a high absorption cross-section of boron is used for... H Donya,M Umer 被引量: 0发表: 2023年 Polyethylene moderator optimized for increasing thermal neutron flux in the NASBEE accelerator...
BNCT is particularly promising for treating locally invasive malignant tumors due to the high neutron-capture cross-section of 10B and the short ranges of its resulting alpha particles and recoiling 7Li nuclei [1]. These high linear energy transfer (LET) particles, with LET values of approximatel...
