6 FAQs about [Average solar neutrino energy]

What is the average energy of solar neutrinos?

The average energy of solar neutrinos is determined to be ∼0.53 MeV and corresponds to 2% of the total energy produced. Hydrogen burning in the Sun works through the so-called pp-chain (∼99%) and CN-cycle (∼1%). The experimental search for solar neutrinos started in 1968 with the Homestake detector , .

What are solar neutrinos?

Neutrinos in (1), when coming from the Sun, are named solar neutrinos. The average energy of solar neutrinos is determined to be ∼0.53 MeV and corresponds to 2% of the total energy produced. Hydrogen burning in the Sun works through the so-called pp-chain (∼99%) and CN-cycle (∼1%).
