We investigate theoretically various dynamical phenomena occuring when
a Bose-Einstein condensate is transfered from a magnetic trap
to an optically confined region of space.
In particular we study
the time dependent Gross-Pitaevski equation describing the process
of loading of the condensate from a harmonic magnetic trap to a cylindically
shaped optical trap. We search for conditions for
observing condensate self-interference,
collapses and revivals, thermalization and randomization of the motion.
We investigate also reflections of the condensate from an optical mirror,
leading to splitting of the condensate wave packet.
