We propose and analyze a scheme to create dark solitons and vortices i
n Bose-Einstein condensates. This is achieved starting from a condensa
te in the internal state \n) and transferring the atoms to the interna
l state \b) via a Raman transition induced by laser light. By scanning
adiabatically the Raman detuning, dark solitons and vortices are crea
ted.
