lithium 7The polarization of Li 7(p, n)Be 7 neutrons has been measured at nine proton energies between 4 and 10 MeV. The dependence of the polarization on reaction angle was determined at 4.0, 4.7, 5.9, 6.9, 7.9, 9.1 and 10.0 MeV. The polarizations were deduced from the asymmetry of...
Thick target neutron yields for the 7Li(p,n)7Be reaction near threshold Transportable accelerator sources of epithermal neutrons are crucial for the development of hospital-based boron neutron capture therapy (BNCT) as a treatm... CL Lee,XL Zhou - 《Nuclear Instruments & Methods in Physics Rese...
Polarizations of the neutrons emitted at 50° in the reaction 7Li(p, n)7Be were obtained in 50 keV steps for proton energies from 3 to 4 MeV to an accuracy of 0.014 for the no group. The solenoid spin-precession technique was employed to reduce instrumental asymmetries. Scattering through...

Neutrons and protons from the high-j orbits are found to compete strongly in rotation-alignment, which gives rise to testable effects. Observation of these effects will provide direct information on the single-particle states in the heaviest nuclear mass region. 展开 ...
Energy spectra and angular distributions of protons emitted from the isotopes 54Fe and 56Fe on bombardment with neutrons with an energy of 13路5 Mev have been studied using photographic emulsions. The angular distributions of protons with energy greater than 7 Mev show a marked forward peak ...
In this work, 3-point bending tests and micro-hardness measurements were performed on pure tungsten irradiated with high-energy protons and spallation neutrons in a target of the Swiss Spallation Neutron Source (SINQ). The specimens were irradiated to doses in the range of 1.3–3.5 dpa, with ...
