THE EARLY HISTORY OF NEUTRINO PHYSICS Neutrino physics had its origins in the study of beta decay. Following the discovery of that form of radioactivity in 1899, some thirty years of research presented two baffling mysteries. First of all, how was the electron in the decay produced, since the principles of quantum mechanics did not permit an electron to exist in the nucleus? Secondly, the continuous energy spectrum of the electrons represented an apparent In this edition of the Newsletter, we are celebrating the breakdown of the principle of the conservation of energy. Only detection of neutrinos from the very core of the Sun. Our at the endpoint of the spectrum was the full energy present, UMass colleagues Andrea Pocar, Laura Cadonati, and Keith Otis, working in Italy with an international team, are as required by energy conservation principles. In the lower credited with this discovery. At the same time we provide energy parts of the spectrum, energy was apparently missing. a complementary article on prior work in neutrino physics.

The small probability for neutrino absorption makes this a very difficult experiment, but in 1956 Cowan and Reines were successful. Their success depended heavily upon the developments in nuclear technology in the intervening years, especially that of the nuclear reactor. A sandwich-like structure of three liquid scintillators and two tanks of cadmium chloride solution was assembled Neutrinos near the Savannah River Nuclear Reactor. from the beta decays of the neutron-rich uranium fission fragments in almost all cases pass through the apparatus, but in a very few cases they are absorbed on the protons of the water in the cadmium chloride tanks. The result in each case after absorption is the production of a neutron and a positron.

Irene Curie and Frederic Joliot were the first to observe this process in 1933. The positron had previously just been discovered by Anderson.

She designed the UMass Sunwheel, which is a circle of tall standing stones arranged so that at sunrise and sunset on the solstices and equinoxes the stones are aligned with the sun (see back cover). For each solar event Judy gave public lectures at the Sunwheel and explained the literally larger picture to hundreds of people. Judy had the knack of not only explaining the astrophysics, but further communicating her appreciation of, and joy about, the amazing scope of nature. As she told her Astronomy talk about the 100 students, “We good things of the Universe.”......
