作者简介
[英]保罗·尤尔特(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.

精彩内容
本书是一部英文版的物理学教材，对原子物理学的简明论述，覆盖性强且有深度，在简要介绍了一些基本概念之后，我们了解微扰理论方法遵循了相互作用的层次结构，该层次结构从优选的相互作用开始，即电子与原子核的库仑静电场的相互作用。很外层电子的自旋和角动量之间，原子核和外部磁场之间的其他相互作用，书中是按它们强度递减的顺序来进行阐述的。将发射或吸收的原子辐射的观察结果与它们所涉及的内部能级相关联来获得光谱学的观点，这是人们通常的做法。之后我们再根据很内层电子的能级来讨论Ⅹ射线光谱，很后，我们简要介绍了一些基于激光的现代光谱方法，该方法可用于对原子结构的很精细细节的高分辨率研究。
