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 ...
Kinematical constraints of helicity amplitudes
(Elsevier, 1969-07-15)
The kinematical constraints of helicity amplitudes are studied using the general ideas of Jackson and Hite. The helicity amplitudes are expressed in terms of a Taylor series expansion from which all constraints at threshold ...
Effects of Random Manufacturing Errors on the Performance of Contemporary Coherent Radiation Sources.
(2014)
The traveling wave tube (TWT) is a linear beam microwave vacuum electron device (MVED) and is a key element in telecommunication systems, satellite-based transmitters, military radar, electronic countermeasures, and ...
The electronic spectrum of fullerenes from the Dirac equation
(Elsevier, 1993-10-04)
The electronic spectrum of sheets of graphite (plane honeycomb lattice) folded into regular polyhedra is studied. A continuum limit valid for sufficiently large molecules and based on the tight-binding approximation is ...
Heavy particles and the [varrho] parameter in the standard model
(Elsevier, 1981-11-09)
A new formalism is presented for the calculation of the contribution [delta][varrho] to [varrho] = Mw2/Mz2cos2[theta]w from heavy particles transforming according to arbitrary representations of SU(2) x U(1). A conjecture ...
High accuracy determination of the shape of the efficiency curve of the HPGe detector in the energy range 900 to 1300 keV
(Elsevier, 1994-12-30)
A method for high accuracy characterization of the shape of a High Purity Germanium (HPGe) detector efficiency curve has been developed. Radionuclides with decay schemes having at least two [gamma] lines, for which the ...
The University of Michigan cyclotron facility for research in nuclear structure
(Elsevier, 1974)
A number of improvements have been made in The University of Michigan 83" sector focused cyclotron since its original construction. The reasons for the changes and the resulting improvement in the production of stable ...
