Query: Twisted electron impact single ionization coincidence cross-sections for
  noble gas atoms   We present the angular profiles of the triple differential cross-section
(TDCS) for the (e,2e) process on the noble gas atoms, namely He (1s), Ne (2s
and 2p), and Ar (3p) for the plane wave and the twisted electron impact. We
develop the theoretical formalism in the first-born approximation. The present
study compares the TDCS for different values of orbital angular momentum number
$m$ and opening angles $\theta_p$ of the twisted electron beam with that of the
plane wave beam. In addition, we also investigate the TDCS for macroscopic
atomic targets to explore the influence of opening angle $\theta_p$ of the
twisted electron beam on the TDCS. Our results show that the peaks in binary
and recoil region shift from the momentum transfer direction. The results also
show that for larger opening angles the peaks for $p$-type orbitals split into
double-peak structures which are not observed in the plane wave results for the
given kinematics. The angular profiles for averaged cross-section show the
dependence of TDCS on the opening angles which are significantly different from
the plane wave TDCS.
