Q: The Goesgen experiment used a nuclear reactor to observe their spectra. Experimental setups to study
these down to the 6.5 megavolt range usually only observe B8 products. Their dynamics show large and
small mixing angle solutions. Those dynamics are enhanced by the MSW mechanism. One method for
finding these makes use of large quantities of perchloroethylene such as in the Homestake experiment.
Research has shown that they can undergo flavor oscillations, and these half-integer spin particles are only
affected by the weak force. They were first postulated in the form of their antiparticles by Pauli. For 10
points, name these non-charge-carrying leptons of little mass involved in beta decay.
