Drobyshev Voronezh State University of Architecture and Civil Engineering Поступила в редакцию 15.09.2011 г. <...> Его асимптотическое решение выражено через функцию Грина, которая имеет точное аналитическое представление для однородного электрического поля и кулоновского поля. <...> Ключевые слова: Электронные волны, фотоотрыв, уравнение Шредингера, функция Грина, кулоновское поле, квазиклассическое приближение. <...> The investigation of electronic waves with high degree of coherence in the photodetachment of a negative ion gives a physical basis to develop the holographic electronic microscopy with high resolution. <...> The interference pattern is considered in the framework of steady-state wave approximation. <...> In semiclassical approximation, an outgoing wave is described by the amplitude slowly varying along a trajectory. <...> Quantum description of electron photodetachment from negative ion is formulated on the basis of the inhomogeneous Schrцdinger equation. <...> Its asymptotic solution is expressed in terms of the Green function that has exact expression for the homogeneous electric fi eld and the Coulomb fi eld. <...> It is demonstrated that repulsive Coulomb fi eld is eff ective for extension of the interference pattern at a short distance from an ion. <...> Keywords: Electronic waves, photodetachment, Schrцdinger equation, Green function, Coulomb fi eld, semiclassical approximation. <...> INTRODUCTION In recent years an increasing attention is focused on the physical eff ects of quantum interference. <...> The electronic waves with high degree of coherence became a basis for progress in electronic microscopy with high resolution and for developing a holography with a low energy. <...> This circumstance opens an opportunity for nondestructive observation with the help of a new tool for nanometer scale objects. * Earlier, the analytical theory was developed to explain experimental results for photodetachment microscope where electrons were detached from negative ions in a homogeneous electric fi eld [3—6]. <...> The quantum © Golovinski P. A., Drobyshev A. A., 2012 interference is taken into account in a three-dimensional space, including a caustic surface and shadow zone. <...> The fi rst eff ect is the Wigner law for the electron photodetachment cross section of a negative ion in the vicinity of a threshold. <...> According to this law, the partial <...>
