An equation for the peak-to-total ratio, P, of a germanium detector is proposed in the following form. P = ε_(p)/ ε_(t) + a(V/A) + b(V/A)~(2)/2 where ε_(p)/ε_(t) is the ratio of the photoelectric to the total detection efficiency for a germanium detector, VIA ...
The total efficiency can be determined from the full energy peak efficiency, provided the peak-to-total ratio is known. For a given high purity germanium (HPGe) detector, one can establish an intrinsic peak-to-total (P/T) efficiency curve using a set of measurements performed with "single"...
Full-energy Peak Efficiency and Peak - to - Total Ratio of Well-type HPGe Detectors for Gamma Rays 来自 ResearchGate 喜欢 0 阅读量: 22 作者: MI Abbas 摘要: The Radiation Physics Laboratory, Physics Department, Faculty of Science is currently the only center in Alexandria city that award a ...
aThe traditional utility rate structure is further divided into a strong or a weak function, where the ratio of on-peak to off- peak rates is large or small, respectively. The cost functions used in this study are the total cost that an electrical consumer pays for operating all components ...

The peak-to-total ratio and absolute efficiency of a 5″ dia. × 5″ NaI crystal for gamma-ray energies from 0.4 to 9.2 MeV have been measured by using a magnetic spectrometer to isolate nuclear states which decay by only one gamma transition. Particle-gamma-ray coincidence measurements ...
An equation for the peak-to-total ratio, P, of a germanium detector is proposed in the following form. P=εp/εt+a(V/A)+b(V/A)2/2 where εp/εt is the ratio of the photoelectric to the total detection efficiency for a germanium detector, V/A is the volume-to-surface ratio ...
