论文摘要
1995年，Novosibirsk核物理学研究所的一组物理学家首次能够观察到原子核的库仑领域的光子分裂，并报告了这项实验在两次会议上的初步结果。这是一个非常困难的实验，因为该过程的概率很小。发布了最终结果花了七年的时间。这个故事最近得到了进一步发展。在超长重离子碰撞中观察到的大型强子对撞机的地图集检测器与光子分裂 - 光散射相关的过程。此外，一支意大利，波兰和英国天体物理学家团队获得了第一个观察性的证据，表明在孤立的中子恒星的磁场中存在真空双折射 - 另一种物理现象也与光子裂解有关。这些新的发展引发了几年前写的这篇文章。
In 1995, a team of physicists from the Budker Institute of Nuclear Physics in Novosibirsk was able to observe the splitting of a photon in the Coulomb field of an atomic nucleus for the first time, and reported the preliminary results of this experiment at two conferences. This was an extremely difficult experiment as the probability of the process is very small. It took another seven years to publish the final results. This story has been further developed recently. The ATLAS detector at the Large Hadron Collider observed in ultra-peripheral heavy ion collisions a process related to the photon splitting - light by light scattering. In addition, a team of Italian, Polish and British astrophysicists obtained the first observational evidence of the existence of vacuum birefringence in the magnetic field of an isolated neutron star - another physical phenomenon also related to the photon splitting. These new developments triggered this essay, written several years ago.
