W. ; Daibog, E. I. ; Kurt, V. G. ; Stolpovskii, V. G. Abstract We have calculated ratios of peak E greater than 70 keV interplanetary electron fluxes to E greater than 55 keV hard X-ray fluences from solar flares observed in 1981-1983 by the Venera 13 and Venera 14 spacecraft to determine the escape efficiencis for nonrelativistic electrons. We used observations from the Solwind coronagraph to determine whether a coronal mass ejection (CME) accompanied each flare. We find that the escape efficiencies of nine events associated with CMEs are similar to those of the eight events not associated with CMEs. This indicates that the population of nonrelativistic electrons produced by a CME-driven shock is at most comparable to the population of nonrelativistic electrons escaping from the associated flare. However, an extended electron injection phase is not considered, and there is at least one well-observed counterexample of an electron event produced in a coronal shock.
