Differential Cross Sections for Compton Scattering Off the Proton at 185 MEV
… with a high resolution, total absorption N ai scintillation detector. The resolution of the detector was sufficient to exclude Π° de-cay photons from the region of interest.

Sensitivity Models for [Beta]+/EC Discovery in Large-Volume Scintillation Detectors
… experiments. We use a simulated large-volume scintillation detector modeled on the Super-Kamiokande experiment, fully implementing this detector in RAT/Geant4. This allows us to extract authentic spectra for the experimental signature of the [Beta]+/EC decay in 124Xe, paving the way for future …

Photon scattering from 40Ca and 39K up to 14 MeV
… photons of resolution 60 to 200 keV and a NaI scintillation detector. Strength was seen at 6.9 and 10.3 MeV. The strength at 10.3 MeV was assumed to be due to a single line, and angular distribution and resonant absorption experiments were done on it. Nuclear resonance fluorescence was measured …

Development of a semi-autonomous directional and spectroscopic radiation detection mobile platform
… robot equipped with a single high resolution scintillation detector to quickly survey an area and convey information about local sources of gamma radiation to a remote human operator. This is achieved by surrounding the detector with a lead sheath that blocks all gamma rays except those …

Resonant elastic photon scattering from the nuclei 88Sr, 89Y, and 90Zr
… photons of resolution 60 to 150 keV and a NaI scintillation detector. Total cross sections were inferred from the elastic cross sections using assumptions of level density, distribution of widths, and average total width. Nuclear resonance fluorescence spectra were taken using incident …

Residual stress in Pt coatings under thermal influence
… for the investigation was a Ψ-goniometer with a scintillation detector. The measured data were analysed with "sin²Ψ"-method. The total stress yielded was found to be a superposition of both the thermal and intrinsic stress in the layer. Analytical model, following the method of Tsui and Clyne, …
