We report R-matrix calculations of doubly-excited 3Σg− states of molecular hydrogen corresponding to 3d̃πnℓ̃π configurations. These states form Rydberg series converging to the 3d̃π series limit. They lie in the continuum of the doubly-excited states of 3Σg− symmetry built on the 2p̃π ion core, and therefore they are autoionized. Calculations of resonance positions and widths are presented.
