[en] A final report is presented on the activities of Task B of the Experimental High Energy Physics Group at the University of California, Irvine. The report deals primarily with a description of and results from the Task B group's major project, the DELCO experiment at the Stanford Linear Accelerator Center. This experiment consisted of a study of direct electrons produced in e⁺e^- collisions at SPEAR. Also discussed are two other experiments engaged in by this group: a study of particular final states produced by long-lived neutral kaons in hydrogen, and a search for massive muon pairs produced by K⁰/sub L/ on a copper target. A list of publications is included
