Monochromators and Imaging Energy Filters,l composition, and the local electronic states of real objects whose structure deviates from ideal crystalline periodicity. To obtain detailed information on the interatomic bonding, an energy resolution of about 0.1 eV is necessary. The presently available electron microscopes do not fulfill this r

Relativistic Electron Motion and Spin Precession,d-particle optics. However, there is no convincing reason that prevents one from incorporating the spin into the formalism of relativistic mechanics if an appropriate interaction Hamiltonian is found. To achieve a proper calculation procedure, it is advantageous to describe the relativistic motion a

Economic Theory, Welfare and the State described most appropriately in light-optical terms, which have been es tablished at a time when charged particles were still unknown. The treatment of particle motion by means of optical concepts has been proven extremely useful for the design of beam-guiding systems, the electron microscope in pa

This discrepancy, which requires an empirical . = 2, can only be explained by means of the relativistic electron theory of Dirac . The spin . of the electron is comparable with the . of t

S. Quiroga,Z. Fernández-Haddad,C. Suáreze system, as schematically illustrated in Fig. 3.1. In order that we can develop the curved sections into a plane, the torsion of the curved axis must be zero. In this case, all sections, which contain the centers of curvature of the optic axis, are ...Charged particles must propagate in vacuo. The

In this case, we can describe the prop
