粒子分裂为两个光子的选择规则是从旋转和反转下的不变性的一般原理推导出来的。对于自旋小于2的初始粒子，光子的偏振态完全由选择规则固定。这些结果不依赖于对相互作用的任何特定假设，可能提供一种判定衰变为双光子的介子对称性的方法。
Selection rules governing the disintegration of a particle into two photons are derived from the general principle of invariance under rotation and inversion. The polarization state of the photons is completely fixed by the selection rules for initial particles with spin less than 2. These results which are independent of any specific assumption about the interactions may possibly offer a method of deciding the symmetry nature of mesons which decay into two photons.
