Query: Scattering of an exponential pulse by a single atom   We discuss the scattering of a light pulse by a single atom in free space
using a purely semi-classical framework. The atom is treated as a linear
elastic scatterer allowing to treat each spectral component of the incident
pulse separately. For an increasing exponential pulse with a dipole radiation
pattern incident from full solid angle the spectrum resulting from interference
of incident and scattered components is a decreasing exponential pulse.
