  We propose and analyze a scheme to create dark solitons and vortices in
Bose-Einstein condensates. This is achieved starting from a condensate in the
internal state $|a>$ and transferring the atoms to the internal state $|b>$ via
a Raman transition induced by laser light. By scanning adiabatically the Raman
detuning, dark solitons and vortices are created.
