| 内容記述 | Photon vortices caring orbital angular momentum (OAM) are one of most interesting topics in various fields of physics. It is expected to create in astronomical systems such as black holes and neutron-stars. Recently it has been planned to generate gamma-ray vortices in the MeV region experimentally. However, there is a question, how to verify the gamma-ray vortex in actual experiments because the optical devise such as holographic phase plates cannot be used. In this work we consider the coincidence measurement of photon vortices on rest electron. The differential cross section of the scattered photon measured simultaneously with the scattered electron for the incident photon with wave function of Laguerre Gaussian (LG) is calculated in the framework of relativistic quantum mechanics. Here, we set the coordinate that the photon beam direction is z-direction, and the scattered electron in the zx-plane. When the initial photon is the plane wave, the final photon is scattered in zx-plane and its energy is fixed. When the initial photon is gamma-vortex, its momentum has y-component, and its energy is not fixed. Here, we define the angle θy as the angle between the final photon momentum and zx-plane, and ΔE as the energy difference in the final photon between the vortex wave and the plane wave for the initial photon. |
