Query: Escape of quantum particles from an open cavity   A negative ion irradiated by a laser provides a coherent source of electrons
propagating out from the location of the negative ion. We study the total
escape rates of the electrons when the negative ion is placed inside an open
cavity in the shape of a wedge. We show the wedge induces significant
oscillations in the total escape rates because of quantum interference effects.
In particular, we show, for a wedge with an opening angle of {\pi}/N, where N
is an arbitrary positive integer, there are (2N - 1) induced oscillations in
the rates. As a demonstration, the case for a wedge with an opening angle
{\pi}/5 is calculated and analyzed in detail.
