Abstract

The 31Δg and 41Δg Rydberg states of Na2, which dissociate to Na(3s) + Na(4d) and Na(3s) + Na(4f), respectively, have been observed by using high-resolution cw optical-optical double resonance spectroscopy. The potential minima of these two states are separated by 129.74 cm-1 and they have an avoided crossing at 4.09 Å implying significant interaction making them a pair of twins. The results of our observation agree very well with the ab initio calculations.
