| Research Abstract |
Towards the test of the gravity at nano-meter scale, we performed high-resolution photo-association spectroscopy using Bose condensates of ytterbium atoms, and determined the binding energies of 15 ro-vibrational states of various isotopes, with the precision of 500Hz. These precision data were finely analyzed by using several known molecular model potentials, which results in the great disagreement between the measurements and calculations.
