Abstract
A theoretical study of cascade quantum-beat intensity profiles is presented for the case of fine-structure beats. An explicit expression for the beat profiles, in the form of a multipole expansion, is derived using the graphical methods of angular momentum theory. The calculations take into account the possibility for the initial state being polarised. Analogous results for zero-field hyperfine-structure beats are listed.Keywords
