New QCD sum rules for nucleons in nuclear matter are derived from a mixed correlation function of spin-1/2 and spin-3/2 interpolating fields. These sum rules allow a determination of the scalar self-energy of the nucleon independent of the poorly known four-quark condensates. An analysis of these new sum rules in concert with previous nucleon sum rules from spin-1/2 interpolators indicates consistency with the expectations of relativistic mean-field phenomenology. We find M^* = 0.68 ± 0.08 GeV and Σv = 0.31 ± 0.06 GeV at nuclear matter saturation density.
