Quantum Mechanics: An Introduction (3Rev Ed.)

The text Quantum Mechanics - An Introduction has found many friends among physics students and researchers so that the need for a third edition has arisen.

There was no need for a major revision of the text but I have taken the opportunity to make several amendments and improvements.

A number of misprints and minor errors have been corrected and a few clarifying remarks have been added at various places.

A few figures have been added or revised, in particular the three-dimensional density plots in Chap. 9. I am grateful to several colleagues for helpful comments, in particular to Prof.

R.A. King (Calgary) who supplied a comprehensive list of corrections.

I also thank Dr. A. Scherdin for help with the figures and Dr. R. Mattiello who has supervised the preparation of the third edition of the book.

Furthermore I acknowledge the agreeable collaboration with Dr. H. 1. Kolsch and his team at Springer-Verlag, Heidelberg.
