Differential Cross-Section Measurements of Thin-Target Bremsstrahlung Produced by 2.7- to 9.7-Mev Electrons

Backscattering of Gamma Rays from Polyethylene, Aluminum and Lead Slabs

“…5 and 6, comparing with the results of Monte Carlo calculations carried out by Davisson and Beach (7), as well as with experimental values obtained in previous work by one of the authors(•>. It is seen from Fig.…”

Validation of Geant4 Bremsstrahlung models: first results

“…10. The agreement is in general satisfactory, especially considering that the experimental errors discussed in [12] are significant in some cases. It is worth noticing the great similarity of the "Standard" and "Low Energy -Tsai" distributions: from the respective references, it results that the two processes adopt the same modeling approach, nevertheless they apparently duplicate code implementations, instead of exploiting the capabilities of the object oriented technology, which facilitates the code reuse through established design techniques.…”

“…For this purpose a Geant4-based simulation application has been developed to reproduce the experimental conditions: the set-up consists of an electron beam of variable energy impinging on a slab of material of desired composition and thickness; different Bremsstrahlung modeling options can be selected in the simulation execution. The results of the simulation are stored in AIDA [15] The double-differential cross sections concerning the comparisons with [12] are shown in Fig. 1 to Fig.…”

“…An initial set of reference experimental data [12]- [14] has been considered for a first comparison with Geant4 simulation distributions. For this purpose a Geant4-based simulation application has been developed to reproduce the experimental conditions: the set-up consists of an electron beam of variable energy impinging on a slab of material of desired composition and thickness; different Bremsstrahlung modeling options can be selected in the simulation execution.…”

Unfolding Low-Energy Gamma-Ray Spectrum Obtained with NaI(Tl) in Air Using Matrix Inversion Method

“…The inverse matrix method [1][2][3] represents the most straightforward method. The stripping method [4][5][6][7][8] is often applied for Ge detector and is based on a successive subtraction of Compton background from higher to lower channels.…”
