    "abstract": "Localized scattering phenomena may result in the formation of stationary\nmatter waves originating from a compact region in physical space.\nMathematically, such waves are advantageously expressed in terms of quantum\nsources that are introduced into the Schr\\\"odinger equation. The source\nformalism yields direct access to the scattering wave function, particle\ndistribution, and total current. As an example, we study emission from\nthree-dimensional Gaussian sources into a homogeneous force field. This model\ndescribes the behaviour of an atom laser supplied by an ideal Bose-Einstein\ncondensate under the influence of gravity. We predict a strong dependence of\nthe beam profile on the condensate size and the presence of interference\nphenomena recently observed in photodetachment experiments.",
