摘要：

The van der Waals atom-surface attraction, scaling as C(3)z(-3) for z the atom-surface distance, is expected to be valid in the distance range 1-1000 nm, covering 8-10 orders of magnitudes in the interaction energy. A Cs vapour nanocell allows us to analyze the spectroscopic modi. cations induced by the atom-surface attraction on the 6P(3/2) -> 6D(5/2) transition. The measured C(3) value is found to be independent of the thickness in the explored range 40-130 nm, and is in agreement with an elementary theoretical prediction. We also discuss the specific interest of exploring short distances and large interaction energy.
