and Applied Analysis 3 where we assume that the spatial variable x : x, y, z varies in the cubic domain Ω : { x, y, z : −1 ≤ x, y, z ≤ 1}, andΨ x, μ, θ : Ψ x, y, z, μ, θ is the angular flux in the direction defined by μ ∈ −1, 1 and θ ∈ 0, 2π . σt and σs denote the total and the differential cross section, respectively, σs μ′, φ′ → μ, φ describes the scattering from an assumed pre-collision angu...

New results of spin polarization of both photoelectrons and Auger electrons are reported after 5p photoionization of free Ba atoms with circularly polarized light. A substantial polarization transfer from the spin polarized photons to the spin polarized photoelectrons and via the hole state orientation to the spin polarized Auger-electrons is observed. The cross comparison of the results for ph...

The dynamics of double ionization (DI) of helium by ion impact has attracted widespread interest in the last decades, in particular, as electron-electron correlation effects play a much more important role than in single ionization (SI). Kinematically complete studies of DI, i.e. experiments recording the full momentum vectors of all involved particles, are very demanding due to the relatively ...

Injuries and the law are connected in many important ways. The law can be a powerful tool for reducing the risk of injury (1). Laws can compel certain individual behaviors, such as seatbelt use, and prohibit other behaviors, such as speeding, to protect the safety of us all. Laws can also require product manufacturers to design and market their products in a manner that will reduce the likeliho...
