What is the Best Textbook for Introductory Atomic Physics?

[TeTeC]

Hello,

I'm a third year physics student. I am looking for a good textbook on introductory atomic physics, considering the fact that I've already had some advanced non-relativistic quantum mechanics courses.

I don't ask for much. A title and a very short explanation on why you think this book is the best will do fine.

Thanks a lot!

The best book I found on atomic physics is the book by Bethe and Salpeter, but it is advanced. Every time I need to look up the lifetime of atomic levels and transitions (e.g., 2p -> 1s) in hydrogen, I go to this book. I have forgotten whether it covers the Lamb shift.
