For initial operation before evaluating gamma-ray detector performance of the Sb[I.sub.3] detectors, [sup.241]Am alpha-particle energy spectra were recorded using the Sb[I.sub.3] detectors in a conventional measurement system comprising a preamplifier, bias supply, shaping amplifier, and a multichannel pulse-height analyzer.
We present analysis of the influence of the external magnetic field on the energy spectra of both on- and off-axis in circular and elongated volcano-shaped quantum dots.

[15] analyzed the wavelet packet energy spectra for blasting vibration signals through utilizing the technique of the wavelet packet analysis.
In summary, we preliminarily explored the correlations between parameters of DSCT/dual-energy imaging such as energy spectra and NIC and the differentiation degree of lung adenocarcinoma.
The nonuniqueness of the two single-wavenumber representations of the nonlinear energy in the MMT model results in the different appearances of energy spectra and energy budgets, which stem mainly from the nonlocal interactions among modes.
Students who complete the course should be able to select the proper detector given the energy and type of particle to be counted and the purpose of the measurement; analyze the results of counting experiments, that is, calculate errors, smooth results, unfold energy spectra, fit results with a function, and so on; and perform radiation measurements following proper health physics procedures.
In the past, single-source dual energy images acquired with these methods were excluded from routine clinical use because the X-ray tube did not emit the two energy spectra simultaneously, but rather in succession through rapid switching or spectral separation at the detector side.
Measurement of one-dimensional energy spectra at different distances above the base, at a distances of [xi] = 0.05, 0.5,1, and 2 cm, respectively, was performed.
To study the energy spectra of extracted ions at work on hydrocarbons and organ silicon compounds, the technique with a multigrid energy analyzer probe described in our previous studies [12] was used.
The design and construction of the proposed new simulated NORM sample and the subsequent energy spectra characterization measurements are presented as part of this work.
