2 00 9 Ionization of Rydberg atoms by blackbody radiation
We have studied ionization of alkali-metal Rydberg atoms by blackbody radiation (BBR). The results of theoretical calculations of ionization rates of Li, Na, K, Rb and Cs Rydberg atoms are presented. The calculations have been performed for nS, nP and nD states for principal quantum numbers n=8-65 at ambient temperatures of 77, 300 and 600 K. The calculations take into account the contributions...

We have studied an ionization of alkali-metal Rydberg atoms by blackbody radiation (BBR). The results of the theoretical calculations of ionization rates of Li, Na, K, Rb and Cs Rydberg atoms are presented. Calculations have been performed for nS, nP and nD states which are commonly used in a variety of experiments, at principal quantum numbers n=8-65 and at the three ambient temperatures of 77...
متن کاملRydberg atom spectroscopy enabled by blackbody radiation ionization
We have excited helium atoms from their metastable 2 3S state to Rydberg states in the range 13 < n < 50 in a two-step process via the 3 3P state using light at λ = 389 nm and 785–815 nm. Atoms in a thermal beam (100 K) cross partially overlapping laser beams of the appropriate frequencies in the counterintuitive order to exploit the high efficiency of stimulated rapid adiabatic passage. The in...
متن کاملBlackbody-radiation-induced resonances between Rydberg-Stark states of Na
We report on measurements of the population of Rydberg states of Na in a constant electric field that result when 300-K blackbody radiation induces transitions from initial states with umu50,1 to neighboring states. Our measurements included comprehensive ranges of initial states (ni*524–29!, repopulation times (td50–50 ms!, and fields (Fs5175–712 V/cm!. We find that the population is redistrib...
متن کاملLong-range interaction between polar Rydberg atoms
The most attractive and the most repulsive potential-energy curves for interaction between two Rydberg atoms in a broad superposition of internal angular momentum states are studied. The extreme Stark states have the largest dipole moments and provide the dominant contribution to the interaction which is then expressed as a long-range expansion involving the permanent multipole moments Qj of ea...
