Simulation of Twisted Electron Mott Scattering

Recently, several groups have demonstrated the ability to produce coherent vortex beams of electrons. These ``twisted'' beams, generated by imprinting an azimuthal phase dependence via holographic diffraction gratings, are able to carry orbital angular momentum up to O(100h). The possibility of using this twistedness as a degree of freedom in accelerator based scattering experiments presents a potential avenue for direct measurement of the quark OAM contribution to nucleon spin. A more thorough understanding of the differences between planar and twisted electron Mott scattering in the relativistic domain is sought using a wavefunction based simulation.
