Abstract
Stuckey and Kiser1 recently reported an experiment in which they believed that they had produced doubly charged negative ions of oxygen and the three lighter halogens. The method used would have required the doubly charged ions to persist for 10−4 sec or more. This is unlikely on theoretical grounds—which means that the experiment will be all the more important if it is confirmed—and the absolute amount of the doubly charged ions (about 1/10 of the amount of the corresponding singly charged ions) is very surprisingly large.
