套索

Group Theory for Atomic Shellst useful of the latter is the quasispin group whose generators . connect states of identical ., ., . and seniority . in the f shell. The symmetries of products of objects (states or operators) that themselves possess symmetries are described by the technique of plethysms.

Perturbation Theorybling physicists and engineers to obtain approximate solutions of various systems of differential equations 1 ; 2 ; 3 ; 4 ; 5 . For the problems of atomic and molecular structure and dynamics, the perturbed problem is usually given by the time-independent or time-dependent Schrödinger equation 6 ; 7 ; 8 ; 9 ; 10 .

Atomic Spectroscopyomic spectroscopic data..Experimental techniques and the details of atomic theoretical methods are not covered in this chapter; these and a number of other subjects pertinent to atomic spectroscopy are treated in one or more of at least fifteen other chapters in this book.

insincerity

Rydberg Atomsor ions and free electrons usually leads to the production of Rydberg states. Second, the exaggerated properties of Rydberg atoms allow experiments to be done that would be difficult or impossible with normal atoms.

Second Quantizationatrix elements of an operator in all configurations may be determined from the knowledge of its matrix elements in but one. This can be viewed as an extension of the usual Wigner-Eckart theorem. The basic concepts of quasispin and quasiparticle are also introduced within this context.

自负的人

Software for Computational Atomic and Molecular Physics a guide to the various software libraries and repositories that can serve the atomic and molecular physics communities. Finally, some topics that generally get little explicit discussion in the literature, but are central to setting up and running a computational research group, are discussed.
