Jack Steinberger

From the Nobel Foundation:

In the decade which followed, the same collaborators, together with Profs. Plano, Baltay, Franzini, Colley and Prodell, and a number of new students, constructed three more bubble chambers: a 12" H₂ chamber as well as 30" propane and H₂ chambers, developed the analysis techniques, and performed a series of experiments to clarify the properties of the new particles. The experiments he remembers with the most pleasure are:

- the demonstration of parity violation in D decay, 1957;
- the demonstration of the ß decay of the pion, 1958;
- the determination of the p⁰ parity on the basis of angular correlation in the double internal conversion of the g rays, 1962;
- the determination of the w and j decay widths (lifetimes), 1962;
- the determination of the S⁰ - D⁰ relative parity, 1963;
- the demonstration of the validity of the DS = DQ rule in K⁰ and in hyperon decays, 1964.

This long chain of bubble-chamber experiments, in which he also enjoyed and appreciated the collaboration of two Italian groups, the Bologna group of G. Puppi and the Pisa group of M. Conversi, was interrupted in 1961, in order to perform, at the suggestion of Mel Schwartz, and with G. Danby, J.M. Gaillard, D. Goulianos, L. Lederman and N. Mistri, the first experiment using a high-energy neutrino beam now recognized by the Nobel Prize, and described in the paper of M. Schwartz.
