Karbunar Lazar^{1, †,}, Borka Duško^{2, ‡,}, Radović Ivan^{2, §,}, Mišković Zoran L^{3, ¶,}

Angular distributions of protons channeled in bent nanotubes when the nanotube curvature angle is α = 4 mrad in the cases of (a) (6, 4) SWNT, (b) (8, 6) SWNT, (c) (11, 9) SWNT, and (d) (15, 10) SWNT. The proton velocity is v = 3 a.u. and nanotube length L = 0.2 μm. In each of the upper panels, the distribution is calculated without the image potential while in each of the lower panel the image potential is taken into account using the extended two-fluid model.
