342 Chapter 10 neutrino oscillations. At the present time, however, this interpretation is not established “beyond reasonable doubt”—a final verdict can be expected from the new experiments currently in preparation. They may be able to discover a characteristic distortion of the neutrino spectrum, or they may actually measure the “wrong-flavored” neutrinos that were produced by oscillations from the ν e originating in the Sun. Contrary to the ν e flux from a power reactor, the solar neutrino spectrum arises from a small number of specific reactions (Fig. 10.1). The main contribution (91%) is from the reaction p + p → d + e + + ν e with a maximum neutrino energy 0.420 MeV (“pp neutrinos”). Second at about 7% of the flux are the “beryllium neutrinos” from the electroncapture reaction e − + 7 Be → 7 Li + ν e with a fixed energy 0.862 MeV. Finally, very small fraction (≈ 10 −4 ) are the “boron neutrinos” from 8 B → 8 Be + e + + ν e . Still, they are of major importance because their large energies of up to 15 MeV allow for a less difficult detection procedure than is required for the soft part of the spectrum. The first solar neutrino experiment is based on the nuclear reaction ν e + 37 Cl → 37 Ar + e − . With a threshold of 0.814 MeV it picks up both beryllium and boron neutrinos, although the argon production rate is dominated by the latter. The target consists of about 4×10 5 liters (615 tons) of perchloroethylene (C 2 Cl 4 ) in a huge tank which is located in the Homestake Mine in South Dakota (U.S.A.), about 1.5 km underground for protection against the cosmic-ray background. After an exposure of a few months to the solar neutrino flux a few argon atoms have been produced (about 0.4 atoms per day). They are chemically extracted and counted by their subsequent decays (halflife 35.0 days). When this pioneering experiment first produced data (Davis, Harmer, and Hoffman 1968) there appeared a deficit relative to the theoretically expected flux, a discrepancy which has persisted ever since—the experiment is still taking data today! On the theoretical side, the ever refined predictions of Bahcall and his collaborators (e.g. Bahcall 1989) were instrumental at establishing the notion that this discrepancy—a factor of around 3—was to be taken seriously. However, in spite of the acknowledged experimental care of Davis and his collaborators, doubt has always lingered about the reliability of the data because this detector has never been subject to an on-off test as the Sun is the only available neutrino source powerful enough to cause a detectable signal. On the solar side, the boron neutrino flux depends crucially on the reaction rate p + 7 Be → 8 B + γ with a cross section that is relatively poorly known.
Solar Neutrinos 343 Fig. 10.1. Solar neutrino flux at Earth according to the Bahcall and Pinsonneault (1995) solar model. Upper panel: Continuum spectra in cm −2 s −1 MeV −1 , line spectra in cm −2 s −1 . Solid lines are the sources of dominating experimental significance. Above: Range of sensitivity of current and near-future solar neutrino experiments. Lower panel: Cumulative spectrum integrated from a given energy to infinity. The situation changed radically when the Kamiokande detector, originally built to search for proton decay, began in 1987 to measure the solar neutrino flux by virtue of the elastic scattering reaction ν e + e − → e − + ν e which is detected by the Cherenkov light emitted by the kicked electron. With a threshold of about 9 MeV (later 7 MeV) it is exclusively sensitive to the boron neutrino flux. Because of its direc-
