Abstract

How the ultracold environment characteristic of modern-day Bose-Einstein condensates (BEC) permits the efficient production of molecular Rydberg states whose vibrational levels are localized at internuclear distances of order 3/2 n2 Bohr radii, with n as the principal quantum number is presented. The formation of these states does not hinge on any of the coherence properties of a BEC, but a condensate provides particularly favorable regimes of temperature and density for their observation. The vibrational binding energies of these levels from n≈20-50 fall in the GHz or MHz range, for molecules excited out of a typical 87Rb atomic BEC.
