论文摘要
我们考虑由扭曲的光子引起的物理过程,从光学(EV)到核(MEV)到高能量伽玛射线(TEV)。我们证明,为了满足角动量的保护,吸收扭曲的光子会导致最终粒子的横向后坐力或颗粒系统的横向后坐力,从而导致反应继续进行所需的阈值能量增加。预计(a)对$^{40} $ ca的感冒离子的光吸收的预测,以及新的横向运动边带,(b)天文学环境中电子峰值的光生产。
We consider physical processes caused by the twisted photons for a wide range of energy scales, from optical (eV) to nuclear (MeV) to high-energy gamma-rays (TeV). We demonstrate that in order to satisfy angular momentum conservation, absorption of a twisted photon leads to a transverse recoil of the final particle or a system of particles leading to increased threshold energy required for the reaction to proceed. Modification of the threshold energy is predicted for (a) Photo-absorption on colds trapped ions of $^{40}$Ca, along with emerging new transverse-motion sidebands, (b) photo-disintegration of deuterium and (c) photo-production of electron-positron pairs in astrophysics environment.
