  Current quantisations of fermions in cylindrical coordinates are shown to be
inadequate in calculating some single-particle expectation values. This paper
develops an alternate quantisation, applicable to one-particle states, which is
generalised to rotating frames in cylindrical coordinates. Using this
quantization, an explicit calculation of the velocity of a flat space free
fermion as observed by a rotating observer is presented. This calculation
demonstrates the validity of this quantisation and the cancellation of
non-inertial rotational effects in the velocity, naively expected from the
mixing of particle and anti-particle field operators.
