    "abstract": "This paper aims to give explicitly all non-linear vacuum solutions to our\nnon-linear field equations, and to define in a coordinate free manner the\nimportant subclass of non-linear solutions, which we call almost photon-like.\nBy means of a correct introduction of the local and integral intrinsic angular\nmomentums of these solutions, we saparate the photon-like solutions through the\nrequirement their integral intrinsic angular momentums to be equal to the\nPlanck\u0027s constant. Finally, we consider such solutions, moving radially to or\nfrom a given center, using standard spherical coordinates.",
