We present a numerical and analytical study of a multimode Jaynes-Cummings
model describing the spontaneous decay of a single atom in a high-Q cavity.
The theory of cavity-modified spontaneous emission is discussed in terms of
quantities that have clear physical interpretations: the photon wave packet
radiated by the atom, its reflection by the cavity boundaries, and its
reabsorption by the atom. Multimode corrections to the single-mode
Jaynes-Cummings model are calculated. The multimode corrections are
formulated in terms of quantities that may be calculated by solving the
single-mode equations of motion.
