Neutron capture cross sections of 136,138,140,142Ce and the decays of 137Ce

Creator:: Torrel, S. and Krane, K. S.
Abstract:: The activation method has been used to measure the cross sections for radiative capture of neutrons by all isotopes of stable Ce (mass numbers 136, 138, 140, and 142). Both the thermal cross sections and the resonance integrals have been determined from separate irradiations with thermal and epithermal neutrons, wherever...

Neutron capture cross sections of 184,189,190,192Os and the decays of 185Os,190Osm, 191Os, and 193Os

Creator:: Krane, K. S.
Abstract:: Radiative neutron capture cross sections have been measured for the stable isotopes of natural Os with mass numbers 184, 189, 190, and 192 by observing radioactive decays of the activation products following neutron irradiation of naturally occurring Os. From irradiations of Os samples separately with thermal and epithermal neutrons, independent...

Neutron capture cross sections of 130,132,134,136,138Ba

Creator:: Dauenhauer, A. Y. and Krane, K. S.
Abstract:: Cross sections for radiative capture of neutrons have been measured by the activation technique for stable isotopes of Ba with mass numbers 130, 132, 134, 136, and 138. From separate irradiations using thermal and epithermal neutrons, independent values for the thermal cross sections and effective resonance integrals have been determined....

Gamma-ray energies in the decay of ³⁸Cl

Creator:: Krane, K. S., Keck, M. L., Norman, E. B., and Shivprasad, A. P.
Abstract:: In order to resolve a long-standing discrepancy of some 30 standard deviations between the two most precise previously reported values of the γ-ray energies in the ³⁸Cl decays, we have undertaken a new precision measurement of the decay energies using a variety of different sources for energy calibration. The deduced...

Terahertz transmission ellipsometry of vertically aligned multi-walled carbon nanotubes

Creator:: Paul, M. J., Kuhta, N. A., Tomaino, J. L., Jameson, A. D., Maizy, L. P., Sharf, T., Rupesinghe, N. L., Teo, K. B. K., Inampudi, S., Podolskiy, V. A., Minot, E. D., and Lee, Yun-Shik
Abstract:: We demonstrate time-resolved terahertz transmission ellipsometry of vertically aligned multi-walled carbon nanotubes. The angle-resolved transmission measurements reveal anisotropic characteristics of the terahertz electrodynamics in multi-walled carbon nanotubes. The anisotropy is, however, unexpectedly weak: the ratio of the tube-axis conductivity to the transverse conductivity, sigma[subscript z]/sigma[subscript xy] [similar or equal to]...

Terahertz-wave generation in quasi-phase-matched GaAs

Creator:: Vodopyanov, K. L., Fejer, M. M., Yu, X., Harris, J. S., Lee, Yun-Shik, Hurlbut, Walter C., Kozlov, V. G., Bliss, D., and Lynch, C.
Abstract:: The authors demonstrate an efficient room temperature source of terahertz radiation using femtosecond laser pulses as a pump and GaAs structures with periodically inverted crystalline orientation, such as diffusion-bonded stacked GaAs and epitaxially grown orientation-patterned GaAs, as a nonlinear optical medium. By changing the GaAs orientation-reversal period (504–1277 μm), or...

Abstract:: Production of Kþ mesons in charged-current νμ interactions on plastic scintillator (CH) is measured using MINERvA exposed to the low-energy NuMI beam at Fermilab. Timing information is used to isolate a sample of 885 charged-current events containing a stopping Kþ which decays at rest. The differential cross section in Kþ...
