We present a calculation which produces the additional phase of a matter wave by applying an adiabatically changing optical field to a double-well Bose-Einstein condensate. An examination of the additional quantum phase is proposed through the comparison of the free expansion interference patterns of the perturbed double-well condensate and the pure double-well condensate.
