The stochastic variational method is used to compute the binding energy for positrons attached to the repulsive H 2(A 3? u) state. Attachment occurs for internuclear separations between 1.616 a 0 and 1.818 a 0. At these distances the vertical ionization potential for the H 2(A 3? u) state is close to the positronium binding energy of 0.250 a.u. The maximum attachment energy occurs at 1.67 a 0 and is 0.003532 a.u.
