Inverse Potential Scattering: A Geometrical Approach
(163K, Postscript)

ABSTRACT.  In multidimensional short-range potential scattering the
high energy limit of the scattering operator determines the potential 
uniquely. For given long-range potential the high energy behaviour of the
Dollard modified scattering operator determines the potential uniquely.
We use geometrical, time-dependent methods for the proof and obtain a 
reconstruction formula as well.
