《原子物理學(xué)(英文)》是一部英文版的物理學(xué)教材,對原子物理學(xué)的簡明論述,覆蓋性強(qiáng)且有深度,在簡要介紹了一些基本概念之后,我們了解微擾理論方法遵循了相互作用的層次結(jié)構(gòu),該層次結(jié)構(gòu)從優(yōu)選的相互作用開始,即電子與原子核的庫侖靜電場的相互作用.很外層電子的自旋和角動量之間,原子核和外部磁場之間的其他相互作用,書中是按它們強(qiáng)度遞減的順序來進(jìn)行闡述的.將發(fā)射或吸收的原子輻射的觀察結(jié)果與它們所涉及的內(nèi)部能級相關(guān)聯(lián)來獲得光譜學(xué)的觀點(diǎn),這是人們通常的做法.之后我們再根據(jù)很內(nèi)層電子的能級來討論Ⅹ射線光譜,很后,我們簡要介紹了一些基于激光的現(xiàn)代光譜方法,該方法可用于對原子結(jié)構(gòu)的很精細(xì)細(xì)節(jié)的高分辨率研究。
The aim of this book is to provide a concise treatment of atomic physics. It should give sufficient coverage and depth to provide a sound foundation for further study along the same avenue. I hope that it will also give enough of a grounding to prepare for work in other disciplines that are underpinned by atomic physics such as chemistry, biology and several aspects of engineering science. So, because the book is a short one it can't include a lot of other relevant material. l don't want to make it so that 'we can't see the wood for the trees!' We will, however, occasionally glance down interesting paths without going into exhaustive detail. The focus is mainly on atomic structure since this is what is primarily responsible for the physical properties of atoms. By atomic structure we mean the arrangement of the various energy levels that arise from the quantization of energy and angular momentum of the electrons surrounding the nucleus.
The text is based on lecture notes for a short course that I gave to third year undergraduate students at the University of Oxford. The course covered the syllabus set for the Final Honour Schools Examination in Physics as part of a three-year first degree or a four-year MPhys. It builds therefore on two years of previous study of mathematics and, in particular, of a first course in quantum mechanics. The study of atomic physics began before the invention of quantum theory-a long time before it, if we include the ideas of the Greek philosophers Leucippus and Democritus in the Sth century BC! However, in order to understand atomic physics at the level of this book, we need to have studied quantum theory first. Familiarity with, and a working knowledge of, quantum mechanics is essential. The book will assume that the reader is fairly comfortable with the mathematical methods used to solve the Schrodinger equation for the hydrogen atom and the concepts of wave functions, eigenvalues, expectation values and matrix diagonalization up to the level of first-order degenerate perturbation theory.
Paul Ewart,obtained a BSc and PhD in Physics from Queen's University Belfast and then was an (SERC) Advanced Fellow at the Blackett Laboratory, Imperial College of Science and Technology in London. In 1979 he moved to the Physics Department, Clarendon Laboratory, Oxford University and as a Tutor and Fellow of Worcester College. He has been a Royal Academy of Engineering Senior Research Fellow, a Visiting Fellow at the Joint Institute of Laboratory Astrophysics and Visiting Professor at the University of Colorado in Boulder, USA, a CNRS visiting Fellow at the Ecole Normale Superieure, Paris and a William Evans Visiting Fellow at the University of Otago, New Zealand. His research work has centred on using lasers to study atomic and molecular physics, quantum optics and nonlinear spectroscopy. His current research includes interdisciplinary applications of laser spectroscopy to combustion and environmental physics, He was Professor of Physics and formerly Head of the Department of Atomic and Laser Physics at Oxford University.
