Pro: Die IT-Sicherheitskriterien der ZSIThe theory considered in the previous chapter did not take into account the spin of the particle. We will discuss now how to incorporate spin in the description of the scattering. Since we will be considering electrons we will suppose that the spin of the scattered particle is equal to 1/2 (in the units of ħ).

Electronic Data Interchange und SicherheitIn this chapter some of the approximate methods for cross section calculations will be considered. We do not intend to consider all existing methods, but only those which are mostly used and can be applied to a variety of particular cases. We will compare the results of calculations by various methods and with the experimental data.

Sicherheit in Unix-Netzen (TCP/IP)In this region only elastic scattering is possible. There are a large number of phase shifts and scattering length calculations. One of the most accurate is based on the variational method (Schwartz, 1961) . The wave function of the “electron + atom” system is represented in the form

Inference Control for relational databasesIn this energy region the excitation of rotation is mainly due. to the long range interaction of the electron with the electric multipole moments of the molecule. This was shown first by Gerjuoy and Stein (1955) who took into account only the quadrupole moment. Later their results were extended by Takayanagi and Itikawa (1970).
