  The elastic scattering of twisted electrons by diatomic molecules is studied
within the framework of the non-relativistic first Born approximation. In this
process, the coherent interaction of incident electrons with two molecular
centers may cause interference patterns in the angular distributions of
outgoing particles. We investigate how this Young-type interference is
influenced by the complex internal structure of twisted beams. In particular,
we show that the corkscrew-like phase front and the inhomogeneous intensity
profile of the incident beam can strongly modify the angular distribution of
electrons, scattered off a single well-localized molecule. For the collision
with a macroscopic target, composed of randomly distributed but aligned
molecules, the angular-differential cross section may reveal valuable
information about the transverse and longitudinal momenta of twisted states. In
order to illustrate the difference between the scattering of twisted and
plane-wave beams for both, single-molecule and macroscopic-target scenarios,
detailed calculations have been performed for a H_2 target.
