Abstract :
Summary form only given. We describe measurements of high-resolution spectra and ionization dynamics in a strongly interacting gas of cold Rydberg atoms. Ground state /sup 85/Rb atoms are cooled to a few hundred /spl mu/K in a magneto-optical trap (MOT), and then excited to high Rydberg states by use of a pulse-amplified laser operating near 300 nm. The Rydberg atom density can be higher than 10/sup 10/ cm/sup -3/, depending on the laser power. The laser system produces nearly transform-limited pulses of 8 nsec duration, allowing spectral resolution of about 80 MHz.
