Total attenuation cross sections in four alloys, telphy, dilver P, anhyster DS, and anhyster M, at 32.1, 52, 72.1, 84.3, 145.4, 279.2, and 661.6-keV photon energies are measured in a good geometry setup using two NaI(Tl) scintillation detectors for low and medium energy photons. Experimental total attenuation cross sections are compared with the theoretical values of Storm and Israel and found to be within experimental error. Using the subtraction method, photoelectric and scattering cross sections are obtained at appropriate photon energies and compared with theoretical values. The effective atomic numbers for photoelectric and total gamma-ray interactions are derived and their variation with energy is discussed.

The total photon cross sections in five nickle-based alloys, viz., Superimphy, Inconel, Nimonic-90, Invar, and stainless steel, are measured at photon energies of 32.1, 52.0, 72.1, 84.3, 145.4, 279.2, 320.0, and 661.6 keV in a good geometric setup using two NaI(Tl) scintillation detectors for low- and medium-energy photons. Experimental total photon cross sections are compared with the theoretical values of Storm and Israel and good agreement is found. Using the subtraction method, we obtain photoelectric and scattering cross sections at appropriate photon energies and compare them with the available theoretical values. The total and partial effective atomic numbers are obtained and presented.

Scattering Cross Sections

Total absorption cross sections in the elements C, Al, S, Cu, Zr, Ag, Sn, Ta, Au, and Pb for photons of energies 5.0, 5.9, 6.4, 8.1, 10.6, 14.4, 24.7, 32.9, 36.9, 66.6, and 129 keV are measured using a krypton-filled proportional counter in the energy range 5 to 25 keV and a thin NaI(Tl) detector in the energy range 30 to 130 keV. The measured total absorption cross sections are compared with those of Miller and Greening and McCrary, Plassman, Paekett, Conner, and Zimmermann. The scattering cross sections obtained by interpolation using the Atomic Data Tables are subtracted from the total cross sections to obtain the photoelectric cross sections and these are further compared with the recent theoretical values of Scofield.

Theoretical Results

The total cross sections for electron scattering from He, Ne, Ar, Kr and Xe in the energy range from 100 eV to 10 000 eV have been calculated based on the optical-model potential. Our theoretical results are compared with the available experimental data. The consistency between them is also discussed. At higher energies (over 2000 eV for He, over 5000 eV for Ne, Ar, Kr and Xe), the total cross sections of electron scattering from these atoms are scarce, so our calculations will give a reference for further experimental and theoretical studies.

AbstractWe prove the uniform boundedness of averaged total cross sections or of quantities related to scattering into cones in the semi-classical limit for scattering by two dimensional magnetic fields. We do not necessarily assume that the energy under consideration is in a non-trapping energy range in the sense of classical dynamics.
