Query: The Quantization of Geodesic Deviation   There exists a two parameter action, the variation of which produces both the
geodesic equation and the geodesic deviation equation. In this paper it is
shown that this action can be quantized by the canonical method, resulting in
equations which generalize the Klein-Gordon equation. The resulting equations
might have applications, and also show that entirely unexpected systems can be
quantized. The possible applications of quantized geodesic deviation are to:
i)the spreading wave packet in quantum theory, ii)and also to the one particle
to many particle problem in second quantized quantum field theory.
