The van der Waals atom-surface attraction, scaling as for z the atom-surface distance, is expected to be valid in the distance range 11000 nm, covering 810 orders of magnitudes in the interaction energy. A Cs vapour nanocell allows us to analyze the spectroscopic modifications induced by the atom-surface attraction on the transition. The measured C3 value is found to be independent of the thickness in the explored range 40130 nm, and is in agreement with an elementary theoretical prediction. We also discuss the specific interest of exploring short distances and large interaction energy.
