For this, we use spatially resolved radio-frequency spectroscopy to measure pairing energies spanning a wide range of temperatures and interaction strengths. In the strongly interacting regime where the scattering length between fermions is on the same order as the inter-particle spacing, the pairing energy in the normal phase significantly exceeds the intrinsic two-body binding energy of the system and shows a clear dependence on local densit","authors_text":"Gerhard Z\\\"urn, Igor Boettcher, Luca Bayha, Marvin Holten, Mathias Neidig, Philipp M.
