Abstract
We have measured the locations and widths of the avoided level crossings between (n+3)s states and n,k Stark states in Rydberg Rb atoms with principal quantum numbers n between 16 and 25. We use two-step laser excitation to excite (n+3)s states in the presence of an electric field and observe a change in the number of atoms driven to higher-lying states by blackbody radiation as the electric field is tuned through the avoided level crossings. We have measured both the positions and widths of the avoided crossings. \textcopyright{} 1996 The American Physical Society.
