...other physicists -- Hans Dehmelt of the University of Washington in Seattle and Wolfgang Paul of Bonn University in West Germany -- are to split the remainder of the prize. They were honored for devising ways of "trapping" single electrons and charged atoms known as ions. Paul, 76, won fame for fashioning a vastly improved ion trap. Dehmelt, 67, who studied with Paul as an undergraduate, used such a trap to observe a single ion. Illuminated by laser beams, the imprisoned ion glowed "like a little blue star," he recalled...
...Dehmelt has performed other small miracles as well. By creating an electromagnetic "cradle," he has kept a lone electron suspended in a vacuum for months at a time. He has also succeeded in observing the fabled quantum jump of a single trapped atom as it absorbed energy and then emitted it in the form of light...
