  • In that perhaps-opaque phrase, "cooling" refers to imposing order on a swarm of unruly particles - antiprotons - required for the experiment.

  • As examples, she and Gerson were the first to observe the mass splitting of the charged Sigma hyperons, and she, working with most of the Berkeley exponents of the nuclear emulsion technique, observed the first nuclear interactions of the newly discovered antiprotons.
