Differential cross sections for photoionization of He

Journal of Electron Spectroscopy and Related Phenomena, 1996
Abstract The angular distribution of photoelectrons from He is studied by a hyperspherical close-coupling (HSCC) method. The influence of the doubly excited states on the asymmetry parameter and differential cross sections for the photoionization of He is investigated. The theoretical results agree very well with experimental data.

Differential cross-sections with hard targets

European Journal of Physics, 2005
When the concept of scattering differential cross-section is introduced in classical mechanics textbooks, usually it is first supposed that the target is a fixed, hard sphere. In this paper we calculate the scattering differential cross-section in the case of the hard target being a fixed figure of revolution of any shape.

Differential Ionization Cross Sections

1985
Ionization cross sections play such an important role in so many branches of physical science that a considerable amount of effort has been devoted both to the theoretical and experimental determinations of these cross sections.

Differential cross section of electron-positron bremsstrahlung

Physical Review D, 1985
A formula is given for the doubly differential cross section of electron-positron bremsstrahlung which is exact in lowest-order perturbation theory. Angular distributions and energy spectra of the emitted photon are computed in the center-of-mass system and in the laboratory system.

Differential cross sections for the excitation of mercury

Journal of Physics B: Atomic, Molecular and Optical Physics, 1993
The authors present results of a completely relativistic distorted-wave calculation for the differential cross sections of mercury excited to the 61P1 state by electron impact at energies from 15 to 100 eV. Cross sections are also presented for the excitation of the 63PJ and 71P1 states at 15 and 60 eV.

Contribution of orbiting to differential cross sections

Physical Review A, 1979
An analysis of the differential cross section in the presence of orbiting is given. It is shown that the Regge representation of the scattering amplitude is particularly useful for such a case. The orbiting oscillations in the cross section of H-Hg are very pronounced and they can be described by only a few Regge poles.

Evaluated differential cross-sections for IBA

Nuclear Instruments and Methods in Physics Research Section B: Beam Interactions with Materials and Atoms, 2010
Abstract The evaluation of the cross-sections for any particular reaction consists in the elaboration of the most accurate possible cross-sections through incorporation of the all relevant experimental data in the framework of nuclear physics theory.

Empirical continuation of the differential cross section

Journal of Physics G: Nuclear Physics, 1979
The theoretical basis as well as the practical methods of empirical continuation of the differential cross section into the nonphysical region of the cos theta variable are discussed. The equivalence of the different methods is proved. A physical applicability condition is given and the published applications are reviewed.
