Absolutely continuous spectrum of a class of random non-ergodic 
Schr\"odinger operators.
(154K, Postscript)

ABSTRACT.  We consider a class of random Schr\"odinger operators with 
non-decaying potentials and prove that their absolutely continuous 
spectrum almost surely fills the positive half-line. We establish the 
existence of the wave operators using the trace class scattering theory.
