How to create Alice string (half-quantum vortex) in a vector Bose-Einstein condensate

Abstract
We suggest a procedure how to prepare the vortex with N=1/2 winding number -- the counterpart of the Alice string -- in a Bose--Einstein condensate with hyperfine spin F=1. Other possible vortices in Bose-condensates are also discussed.
