AB: We present a comparison between electron data by WIND/3DP and $^{3}He$ data by ACE/ULEIS. Our study shows that impulsive energetic electron events occur more often than impulsive $^{3}He$-rich events. For a set of 41 $^{3}He$-rich events from 1997 November to 2003 April, WIND/3DP has good measurements during 29 events. An injection analysis shows that among the 29 $^{3}He$-rich events, 13 events with the $^{3}He$/$^{4}He$ ratio ($\sim$0.002-0.34) have an electron event with an injection time difference $<$ 1 hour, 6 events with the $^{3}He$/$^{4}He$ ratio ($\sim$0.081-6.2) have an electron event with an injection time difference of 1-2 hours, and the other 8 events with the $^{3}He$/$^{4}He$ ratio ($\sim$0.0054-0.25) have an electron event with a injection difference $>$ 2 hour or have no electron events. Further analysis including type III bursts and energy spectra may provide important information about the association between $^{3}He$-rich events and electron events.
