Ball lightning (picture)? How is it produced?

Ball lightning is caused by the atomic nuclei of argon and other elements in the air. Under the action of lightning of up to several million volts, a isotopic transformation reaction occurs. When the ball lightning transitions from a low energy state to an excited state, the outside world is transformed. The energy acting on the argon atoms is stored. Metastable nuclides are unstable, have a short half-life, and will decay quickly, transitioning from the metastable state to the ground state, releasing the nuclear energy stored in the nuclide. When a nuclide transitions from a metastable state to a ground state, under the influence of the nuclear field, the energy difference is directly transferred to the electrons in the atom without going through the intermediate link of emitting photons. When the emitted electrons collide with other atoms in the air, they will form a spherical luminous body with a diameter of 5cm~35cm, producing red, blue, cyan, silvery white or even dark blue light.
