A method is developed for the calculation of total scattering cross sections in two-body strong interactions by an algebraic approach using the group SU(1,3). A general discussion of the method, its historical development, and a possible theoretical basis is presented. Total cross sections for a total of 95 events based on 8 parameters are predicted. Only 19 of these cross sections have been experimentally measured. Of these, 7 consist of only l experimental measurement and so cannot be used. The remaining cases are sufficient only to show that the predictions seem to be of the correct order of magnitude.

We define total scattering cross-sections for magnetic Schrödinger operators in two dimensions and prove the shadow scattering (the quantum total cross-sections double the classical ones in the semi-classical limit) under some assumptions.

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.

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.

Theoretical Results

Photoelectric cross sections for 52.2 and 84.3 keV photons in Al, Cu, Zr, Ag, Sn, Ta, Au, and Pb are obtained by subtracting the total scattering cross sections from the measured total absorption cross sections. The scattering cross sections are taken from the recent tabulated values of Veigele, for subtracting purpose. The results are compared with the values interpolated from the theoretical results of (1) Schmickley and Pratt and (2) Scofield.
