We show that in a two-component Bose gas with Rashba spin-orbitcoupling two atoms can form bound states (Rashbons) with anyintra-species scattering length.At zero center-of-mass momentumthere are two degenerate Rashbons, but the degeneracy is lifted atfinite in-plane momentum by two different effective masses.Underproper conditions, particularly with weakly attractive intra-speciesinteraction and repulsive inter-species interaction, a stableRashbon condensation can be formed below a critical temperature.
