Semi-empirical efficiency equations for Ge(Li) detectors

Measurement of the 4f strong interaction level width in light antiprotonic atoms

“…The detection efficiency as a function of energy was determined by fitting a semi-empirical formula for Ge(Li) detectors (Eq. (8) in [3]) to the experimental data (Fig. 1).…”

Applicability of the analytical functions and semi-empirical formulae to the full energy peak efficiency of large volume HPGe gamma detectors

“…It is appropriate to mention that, as expected, Owens [2] noted that the approach followed by Hajnel and Klusek [17], in which, in addition to the photoelectric effect, multiple Comption scattering and pair production process are also taken into account, provided the most accurate prediction of the FEPE of Ge(Li) and HPGe detectors, and over the largest energy range as well. Unfortunately the fact that this particular semi-empirical formula involves twelve parameters and quite some computation, limits its convenient use, and therefore we did not attempt to use it for our data.…”

Compton scattering I: Angular distribution and polarization degree

“…This phenomena was treated by several methods : Wächter, et al (1960) used it in Monte Carlo calculations for total and peak efficiencies of spherical NaI detector, Wainio and Knoll (1966) used it for characteristics the response of fully depleted silicon and germanium detectors, Lal and Iyengar (1970) and Grosswendt and Waibel (1975) used it in explain the energy peak and the double escape peak efficiencies for right circular cylindrical Ge (Li) detectors and Gaggero (1971) used it in for the photo-fractions calculation. Paradellis and Hontzeas (1969), Mowatt (1969), Hajnal and Klusek (1974), and Moens et al (1981) were deduced semi-empirical equations to obtain the relative full energy-peak efficiency of a Ge (Li) detector based on it. Freeman and Jenkin (1966) were obtained empirically the relative total-energy-peak efficiencies over the gamma-ray energy range 500 to 1500 keV for any given Ge (Li) detector depend on it.…”
