Three-jet events produced in e/sup +/e/sup /minus// annihilations are used to provide comparisons between quark and gluon jets. Differences between quark-induced and gluon-induced jets are observed. Quark jets tend to have a more tightly collimated structure than gluon jets, which is reflected in the concentration of a larger fraction of the jet's energy near the jet axis. These properties can be used to enhance signals for new particles produced in e/sup +/e/sup /minus// and hadron colliders, and discriminate against QCD backgrounds from gluon jets. 11 refs., 4 figs.
