γ - photon and electron e - The collision produces a pair of neutrinos Antineutrino The reaction is , at the right end of the equation It can also be promoted to ﹐ Etc. It is shown as follows: 
Photoneutrino process This is a process in which the electromagnetic effect of electrons absorbing photons is combined with the weak effect transmitted by the intermediate boson. The overall effect of this process is that a photon is transformed into a pair of positive and anti neutrinos. The produced neutrino pair is the same as the matter only Weak interaction , extremely penetrating, with the escape of neutrino pairs, the energy of the system is taken away. In stars, as the temperature increases, the proportion of high-energy photons and electrons becomes larger and larger, so the probability of photoneutrinos and the energy loss caused by them become larger and larger. Theoretical calculation shows that the energy loss is proportional to the eighth power of temperature. When the temperature inside a star reaches 100 million degrees, the energy loss caused by the process of light generated neutrinos becomes an important factor in the evolution of the star. Compared with other processes of radiation neutrinos, the density of photogenerated neutrinos is less than 10 five G/cm three The temperature is lower than 4 × 10 eight The main process is in the range of degrees (see electron pair annihilation neutrino process).
