Abstract
We theoretically introduce the method for detecting the atomic vortex (AV) of a helium atomic beam. The AV detection is based on near-field diffraction. The simulations relied on the Feynman path integral. The Gaussian beam and velocity distribution of helium atoms are taken into account. Gravitational field is also included in this study. This research can be useful in the field of matter-wave optics.
