Query: Structure of resonances in a square well potential   We study the structure of resonances as derived from the exactly solvable
Lippmann-Schwinger equation for a one-dimensional square well potential. Within
this framework, we discuss the concept of resonance form factors, and the
relation of the corresponding spatial densities to ``resonance wave
functions''.
