- Why was the Davis experiment only able to detect one-third of the neutrinos originally predicted? Most of the neutrinos were absorbed by Earth’s atmosphere. The neutrinos combined with other particles as they entered Earth’s atmosphere. The neutrinos distributed evenly among three different flavors while traveling to Earth. The number of neutrinos was too great to be held in the tank that Davis designed. The other two-thirds of neutrinos dissipated while traveling to Earth.The half-lives of 235U and 238U are 7.04 × 108 years and 4.47 × 109 years, respectively, and the present abundance ratio is 238U>235U 5 137.7. It is thought that their abundance ratio was 1 at some time before our earth and solar system were formed about 4.5 × 109 years ago. Estimate how long ago the supernova occurred that supposedly produced all the uranium isotopes in equal abundance, including the two longest lived isotopes, 238U and 235U.Explain the process of electron-holes recombination.
