In this captivating biography, Patricia Rife interprets both the life and times of Lise Meitner (1878-1968), the female physicist at the heart of the discovery of nuclear fission. She was a colleague and friend of many of the giants of 20th century physics: M. Planck, her Berlin mentor, A. Einstein, M. von Laue, Madame M. Curie, J. Chadwick, W. Pauli, and N. Bohr. Meitner was the first woman to earn a Ph.D. in physics at the University of Vienna, a pioneer in the research of radioactive processes and, together with her nephew Otto Robert Frisch, an interpreter of the process of nuclear fission in 1938. Yet at the end of World War II, her colleague of thirty years, radiochemist Otto Hahn alone was awarded the 1944 Nobel Prize in Chemistry for the "discovery" of nuclear fission -- a discovery based on years of research in which Meitner was directly involved before her secret escape from Nazi Germany.
Quantum mechanics provides the fundamental theoretical apparatus for describing the structure and properties of atoms and molecules in terms of the behaviour of their fundamental components, electrons and nuclei. For heavy atoms and molecules containing them, the electrons can move at speeds which represent a substantial fraction of the speed of light, and thus relativity must be taken into account. Relativistic quantum mechanics therefore provides the basic formalism for calculating the properties of heavy-atom systems. This book provides a detailed description of the application of relativistic quantum mechanics to the many-body problem in the theoretical chemistry and physics of heavy and superheavy elements. Recent years have witnessed a continued and growing interest in relativistic quantum chemical methods and the associated computational algorithms which facilitate their application. This interest is fuelled by the need to develop robust yet efficient theoretical approaches, together with efficient algorithms, which can be applied to atoms in the lower part of the Periodic Table and, more particularly, molecules and molecular entities containing such atoms. Such relativistic theories and computational algorithms are an essential ingredient for the description of heavy element chemistry, becoming even more important in the case of superheavy elements. They are destined to become an indispensable tool in the quantum chemist's armoury. Indeed, since relativity influences the structure of heavy atoms in the Periodic Table, relativistic molecular structure methods may replace in many applications the non-relativistic techniques widely used in contemporary research.
