“…Detector efficiencies were obtained from a set of calibrated y-sources covering the energy range from 122 to 1,332 keV. The analysis of all pulse height spectra was performed with the set SAMPO 80 of computer codes [21,22]. The spectroscopic data entering into this calculation are shown in Table 1.…”

Excitation functions of the reactions l~ xn) and mCd(p, xn) have been measured with stacked foil techniques for projectile energies E<__45 MeV and multiplicities x<__4 populating ground and spin isomeric states in 112-XIn. Preequilibrium (PE) contributions are more pronounced for the p than for the 3He entrance channel and for low multiplicities x and can be reproduced with the (geometry dependent) hybrid model. The observed isomeric cross section ratios require a reduced population for the high spin state (as compared with the expectation for equilibrated systems) whenever PE emission contributes significantly. Calculations for a full statistical model with a PE decay mode and approximate angular momentum conservation indicate PE neutron emission to be stretched in angular momentum space. For the (p, xn) reactions a more detailed coupling scheme is imperative whereas the (3He, xn) data suggest the competitive PE emission of complex particles.

“…They were calibrated for absolute efficiencies with a variety of gamma-ray standards: based on the deviations of individual calibration points from a smooth curve the absolute accuracy of the calculations was estimated to be about 5%. The spectra were analysed with computer codes SAMPO [16] and GSAP [17]. The radionuclides were unambiguously identified by their gamma-ray energies, half-lives and fractional abundances 1181.…”

“…These accumulations are updated every second in a sliding window fashion. MISTI uses two peak analysis methods, a standard Region of Interest (ROI) Method and a Second Difference Peak Search (via Genie2K) [6]. The more sensitive ROI method uses a library that defines the ROI of an isotope's relevant photopeaks, as well as left and right background regions, with each background ROI tailored to avoid common background interferences.…”

The Mobile Imaging and Spectroscopic Threat Identification (MISTI) system developed to locate radiological threats in urban and rural environments is currently undergoing characterization activities. MISTI is a mobile source detection and imaging system designed to identify and localize a radiological source to within +/-10m in range. This requirement is based on a 1 mCi Cs-137 source at 100 m in 20s, while maintaining a false alarm rate of less than one per day. MISTI utilizes the cost effective collection power of NaI for imaging and the sensitivity of high resolution HPGe for spectroscopy. MISTI's data acquisition system was developed with the latest commercially availed hardware that met MISTI's requirements. The performance of crucial software and hardware components is presented along with overall system performance. A synopsis and example of the initial characterization results are presented here.
