Quantum Mechanics

About the Book

This book is based on a quantum course taught by the author to graduate students (MS and PhD) at the Physics Department, College of Science, Baghdad University, Iraq, for the period 1978–2007. Also, it is based on the author’s experiences as a researcher and administrator to certain research institutions and scientific organizations. It describes the quantum mechanics as a good tool to deal with studying of the properties of the microsystems (molecules, atoms, nucleus, nuclear particles, subnuclear particles, etc.). Therefore, this book in general deals with the following: 1. The Concept of the Quanta, Plank Experiment 2. Duality Property, De Broglie Hypothesis 3. Photoelectric Effect 4. Double Slits Experiment 5. Wave Mechanics and Schrödinger Equations 6. Heisenberg Concept of the New Mechanics Using the Matrix Concept 7. The Schrödinger and Heisenberg Pictures 8. The Interaction Picture 9. The Theory of Transformation 10. The Operator of Transformation 11. The Generator of the Operator of Rotation 12. The Scattering Theory 13. The Addition of Angular Momenta 14. The Approximation Methods 15. Basic Elements of Relativistic Quantum Mechanics 16. The Introduction to the Field Theory 17. Appendix A: Properties of Delta Function 18. Appendix B: Whitticker Equation Solution 19. Appendix C: Solved Problems

About the Author

Ali A. Abdulla is emeritus professor of nuclear physics at the University of Baghdad, Iraq. He also taught at the University of Basrah and at the Mustansiria University as lecturer. During his PhD work at Oklahoma State University (1965–1968), he also taught from 1967 to 1968. He first worked as a scientific researcher at Iraqi Nuclear Research Center (December 1968) and then director to the institute (1970). In 1975, he was appointed chairman to the physics department at Baghdad University. He used to teach all branches of physics with the emphasis on teaching nuclear physics and quantum mechanics for graduate students. He supervised graduate research works for twenty-five years for both MS and PhD students in the field of nuclear physics. Also, he occupied a scientific directory to some important scientific institutions on the Arab World level. He also used to have scientific relations with some United Nations Scientific Institutions. He published alone and as a coauthor about fifty papers in different international scientific journals. He published books, fifteen books, in physics and general thoughts in Arabic language. Currently, he lives in the United States—in East Lyme, Connecticut—as a permanent resident.
