The Fundamental Particle Dissociation Proof for the Photon Origin Nature of Microscopic Particles

Photon science facilities around the world carry out particle threshold dissociation experiments and reveal consistent and stable physical rules. Electrons can interact and dissociate under visible light and laser low energy photons. Protons can achieve efficient dissociation under high energy gamma photons. In terms of physical principles, the channel for low energy photons to act on protons is fully open. It is only not adopted in experiments due to extremely low energy accumulation efficiency. The photon origin theory system leads to a subversive conclusion. The basic constituent unit of electrons protons and neutrons is gamma photon. Particles are stable energy cages formed by gamma photons through spatial self locking. Two gamma photons collide and generate a pair of positive and negative particles, namely positive negative electron pair or positive negative proton pair. They are generated in pairs instead of two photons merging into a single particle. This generation mechanism determines that a single primary particle cannot contain gamma photons with the same spin direction. A single closed self locking structure can only produce spatial disturbance in one direction. The electron contains counterclockwise spinning gamma photons and produces counterclockwise disturbance, showing one negative charge. The proton contains clockwise spinning gamma photons and produces clockwise disturbance, showing one positive charge. Therefore electrons and protons carry only one type of charge and cannot have two electric properties at the same time. The neutron is not generated by self locking of a single photon. It is a secondary elementary particle formed when a proton captures an electron and merges. It contains two groups of gamma photons with clockwise and counterclockwise spin. The two groups create spatial disturbances in opposite directions and neutralize each other, so the neutron shows no electric property. When an external photon enters a particle cage, it cannot remain as an independent individual. It must merge with the original energy system inside the cage. When a particle releases photons, part of energy is separated from the whole energy system to form photons. It does not directly release independent photons originally stored inside. There are no large numbers of separate gamma photons inside particles. The internal energy system is a unified whole. There exists an energy threshold for gamma photon self locking to form particles. The self locking threshold of electron is about 510 thousand electron volts. This threshold is not absolutely fixed and allows fluctuation within a certain range. Particles have no sub particle secondary structures. Such secondary structures cannot maintain long term stability. Gamma photons inside the cage keep moving at light speed. Spin is the external manifestation of this light speed motion. After photons are locked in the cage, their vibration angle and energy property remain unchanged. Only the spatial form is locked into material particles. This paper further clarifies the core rule of photon absorption by microscopic particles. Whether a photon can be absorbed by a particle depends strictly on matching of vibration angle. Photon energy is determined by its own property. Free electrons have no energy level limits. If the incident photon matches in vibration angle, the free electron can continuously absorb photons and accumulate energy step by step. Whether particle dissociation can be achieved depends on whether accumulated total energy reaches the self locking dissociation threshold. Bound electrons in atoms have discrete energy levels. These levels are external constraints imposed by the atomic nucleus field, not inherent properties of electrons. Bound electrons can absorb photons of corresponding energy to complete energy level transition. They can also absorb photons with energy larger than energy level difference. Excess energy turns into electron kinetic energy. When incident photon energy greatly exceeds atomic binding limit, electrons obtain extra kinetic energy and escape from atoms, which is ionization. Free electrons break away from atomic field constraints and have no discrete energy level limits. If the incident photon matches in vibration angle, free electrons can absorb photons repeatedly and accumulate energy continuously. Continuous energy input feeds the particle. Finally the accumulated energy breaks the self locking threshold and achieves complete dissociation. This research uses repeatable threshold dissociation experiments to fully prove that light can condense into matter and matter can completely revert to light. It builds a complete physical closed loop of mutual transformation between light and matter.
