      abstract     = {We present a detailed analysis of the propagation of
                      high-energy electron beams that have different shapes in a
                      crystal of [100]-oriented zincblende GaN. Our study
                      primarily focuses on Bessel beams and makes use of
                      reformulated Bloch wave and multislice simulations. As a
                      result of the simplicity of the momentum spectrum of a
                      Bessel beam and the symmetry of the crystal, its propagation
                      in the material can be described in a free-space
                      representation, providing a deeper understanding of
                      channeling phenomena and of probe intensity oscillation in
                      the propagation direction. We also consider aperture-limited
                      and Gaussian beams. The latter probes are shown to be
                      optimal for coupling to 1s Bloch states and achieving
                      minimal spreading along atomic columns.},
