We have searched for evidence of $$W' \to e\nu$$ and $$Z' \to ee$$ in data collected with the D0 detector at the Tevatron during the 1992-1993 $$p\overline{p}$$ collider run at $$\sqrt{s}$$ = 1.8 Te V. We set an upper limit at the 95% confidence level on the cross section times branching ratio for $$W' \to e\nu$$, assuming that the neutrino from $W'$ decay is stable and has a mass significantly less than $$m_{w'}$$ and an upper limit on $$Z' \to ee$$. We exclude the existence of a $W'$ of mass less than 610 GeV and a $Z'$ of mass less than 490 GeV at the 95% confidence level, assuming standard model couplings to quarks and leptons.
