Professor Johnson has made outstanding contributions to developing and applying
relativistic correlation theory (relativistic many body perturbation theory)
to atoms,and this book is an excellent modern treatment presented at the 2nd
year graduate student level (i.e. to those who have 1 year of graduate quantum
mechanics).The book is a nice mixture of formalism and computation-seldom seen
in textbooks-which reflects the author's abilities and interests. The price
is quite reasonable.The book should be of interest to quantum chemists,condensed
matter computationalists,nuclear and atomic physicists,as well as those just
interested in the formalism.
