Описание: This book offers an essential compendium of astronomical high-resolution techniques. Recent years have seen considerable developments in such techniques, which are critical to advances in many areas of astronomy. As reflected in the book, these techniques can be divided into direct methods, interferometry, and reconstruction methods, and can be applied to a huge variety of astrophysical systems, ranging from planets, single stars and binaries to active galactic nuclei, providing angular resolution in the micro- to tens of milliarcsecond scales. Written by experts in their fields, the chapters cover adaptive optics, aperture masking imaging, spectra disentangling, interferometry, lucky imaging, Roche tomography, imaging with interferometry, interferometry of AGN, AGN reverberation mapping, Doppler- and magnetic imaging of stellar surfaces, Doppler tomography, eclipse mapping, Stokes imaging, and stellar tomography. This book is intended to enable a next generation of astronomers to apply high-resolution techniques. It informs readers on how to achieve the best angular resolution in the visible and near-infrared regimes from diffraction-limited to micro-arcsecond scales.

Описание: Electron Momentum Spectroscopy measures the energy-momentum density of the electrons in atoms, molecules and solids by means of a kinematically-complete ionization reaction initiated by an electron beam. The construction of spectrometers and the acquisition and reduction of cross-section data are described in detail. The quantum theory of the reaction is explained and the experimental verification is given. It is shown how to extract quasiparticle orbitals, and coefficients describing electron correlations of the data. These quantities are derived from the many-body theory of the electronic structure of atoms, molecules and solids. The relationship to less complete methods of investigating electronic structure is discussed.
Examples are given of the determination of atomic and molecular orbitals and quantities relating them to the observed states of the residual ion. For amorphous, polycrystalline and crystalline solids and surfaces, examples show the energy-momentum density of valence electron bands, and effects due to electron diffraction and plasmon excitation.
The book aims to give a complete account of electron momentum spectroscopy to date. Its significance is that it is a sensitive and experimentally-verifiable test of essentially every aspect of calculations of electronic structure. It is the only such probe available.

Описание: The electron density of a non-degenerate ground state system determines essentially all physical properties of the system. If the functional form of a molecular electron density is known, then various molecular properties affecting reactivity can be determined by quantum chemical computational techniques or alternative approximate methods.
