Abstract
In a Nature LETTER [1], a control of neutron angular momentum was apparently demonstrated
using a neutron crystal interferometer. In the meantime, a number of highly interesting articles
have been published dealing with the n-OAM and neutron interferometry, citing [1]. We show that
the interpretation of [1] having detected a n-OAM is incorrect for several serious reasons and point
out inconsistencies. Based only on the theory of dynamical neutron diffraction, we calculate all the
interferograms and show perfect agreement with those given in [1]. There was no need to assume
an additional n-OAM because no additional effect was observed that could not be explained by
standard theory.
