Abstract

The graphical method of boxes-and-arrows is usually used to describe electronic states and spin-orbit coupling in atoms. This method, as it stands, can only be applied to light atoms (i.e., LS-coupling). We present an analogous method that can be applied to heavy atoms (i.e., the case of jj-coupling). The use of the same graphical method emphasizes the same physical nature of energy terms in both light and heavy atoms.

      A systematic procedure is developed to obtain the electron angular momentum coupling (jj) spectroscopic terms, which is based on building microstates in which each individual electron is placed in a different mj “orbital”. This approach is similar to that ...
