We investigate how Bose-Einstein condensates, whose initial state is eitherirrotational or contains a single vortex, scatter off a one-dimensionalGaussian potential barrier. We find that for low atom densities the vortexstructure within the condensate is maintained during scattering, whereas atmedium and high densities, multiple additional vortices can be created by thescattering process, resulting in complex dynamics and disruption of the atomcloud. This disruption originates from two different mechanisms associatedrespectively with the initial rotation of the atom cloud and the interferencebetween the incident and reflected matter waves. We investigate how thereflection probability depends on the vorticity of the initial state and on theincident velocity of the Bose-Einstein condensate. To interpret our results, wederive a general analytical expression for the reflection coefficient of arotating Bose-Einstein condensate that scatters off a spatially-varyingone-dimensional potential.Comment: 9 pages, 9 figure
