The 12C([alpha], n)15O and 16O([alpha], n)19Ne reactions at E[alpha] = 41 MeV
(Elsevier, 1981-06-15)
Spectra and neutron angular distributions have been obtained for the ([alpha], n) reaction on 12C and 16O to (a) determine whether with this reaction more detailed spectroscopic information can be extracted than from ...
Analysis of the inelastic scattering of 50 MeV protons
(Elsevier, 1968-09-23)
Differential cross sections and asymmetries for 50 MeV proton scattering from vibrational states in 64,66,68,70Zn and 114Cd have been analysed using a collective-model interaction obtained by deforming the entire optical ...
Efficiency and angular resolution calculations for a prototype multiple Compton scatter camera
(Elsevier, 1994-06-15)
Monte Carlo simulations were performed to optimize the layer thickness of a Compton camera which utilizes multiple Compton scatterings. The optimum layer thickness was found to be less than 0.5 mm for 150 keV, 2 mm for 511 ...
Digital techniques for real-time pulse shaping in radiation measurements
(Elsevier, 1994-12-30)
Recursive algorithms for real-time digital pulse shaping in pulse height measurements have been developed. The differentiated signal from the preamplifier (exponential pulse) is amplified and then digitized. Digital data ...
An image intensifier-scintillator device for determination of profiles and images of weak beams of ionizing particles or X-rays
(Elsevier, 1961)
An instrument for determining the shape and intensity distribution of particle and X-ray beams has been developed using an image intensifier tube together with a bundle of filaments of scintillator. A description of the ...
Hydrogen trapping in molybdenum in the presence of radiation damage
(Elsevier, 1981-06)
Hydrogen was implanted in samples of single crystal molybdenum, many of which had been previously damaged by 4He at 18 or 150 keV. The hydrogen implantations were at low energies, usually at 10 keV. Depth profiles (up to ...
Precision energy measurements of gamma rays occurring in the decays of 165Dy and 193Os
(Elsevier, 1971-06-15)
A curved-crystal spectrometer has been utilized to obtain energy measurements of 22 gamma rays between 73 keV and 715 keV occurring in the decays of and . Some of these energy measurements have sufficiently small uncertainties ...
Determination of spectra from pulse-height data
(Elsevier, 1975-04-15)
A method for determining parameters of a physical spectrum from pulse-height data is described. This method is designed to utilize information from the entire range of data and possesses advantages over other methods in ...
Radiation damage in polarized target materials
(Elsevier, 1978-01-15)
We examine some of the parameters which influence the decay of the polarization of polarized targets in an intense proton beam. We find that the usual characteristic flux for the polarization to drop to 1/e of its initial ...
