This new narrow plate design (~ 5mm-thick) minimizes the parasitic loss of thermal neutrons to hydrogen capture because the ~(10)B capture reactions are dominant. Preliminary MCNP calculations identifies optimum ~(10)B deposit thickness and increases in efficiency as a function of the number of ...
Boron neutron capture therapy (BNCT) is based on a lethal 10B(n,α)7Li capture reaction that occurs when 10B is irradiated with low-energy thermal neutrons to produce high energy α-particles and 7Li nuclei. From: Advanced Drug Delivery Reviews, 2008 ...
Levels inN16from the Total Neutron Cross Section ofN15 The total neutron cross section of N15 has been measured for energies from 0.45 to 2.20 MeV. Neutrons with energy spreads between 15 and 30 keV were produc... D.,B.,Fossan,... - 《Physical Review》 被引量: 0发表: 1964年 Total ...
A gas, disposed within a gas-tight container enclosing the plate, insulators and wires, and capable of stopping alpha and Lithium-7 particles and generating electrons produces a signal on the second wire which is detected and subsequently related to the number of neutrons impinging on the plate....
It is worth to mention that 14C is an important time stamping tool, which is also produced mostly in the upper atmosphere by spallation of 14N with secondary cosmic-ray neutrons. After its formation, it is attached with oxygen atoms to form 14CO2, becomes part of global biogeochemical cycle...
While the high mean neutron energy permits 252 Cf to deliver a high LET, low OER dose to tumor on a macroscopic scale, thermalization of neutrons followed by 10 B capture may augment this dose at the cellular level if adequate loading of tumor cells with 10 B is possible. This paper ...
