Abstract

The populations of np forbidden transition states for two-step excitation of Na atom have been obtained by appling the static field of strength 167 V/cm. We have obtained lifetimes of np(n = 19-23) states by the method of delaying ionization in pulsed electric field, and have compared the calculation values with the measured data. The influence of applied fields and environmental radiation on the determination of the lifetimes of the highly excited states were discussed.

INFLUENCE OF ENVIRONMENTAL RADIATION ON LIFETIMES OF STARK STATES IN HIGHLY EXCITED ATOM

FANG DA-WEI, XIE WEI-JUN, Sen Zhang +1 more

The populations of n=17,m=0 Stark states of sodium atom in static electric fields have been obtained by two step excitation using tunable lasers. The lifetimes of some selected Stark states and the influences of blackbody radiation on the lifetimes were measured by using delayed electric field ionization. The measured data were compared with the calculated values. The experimental and theoretical results exhibit following behaviours: The total rates of stimulated emission and absorption transitions induced by environmental radiations are of the same order of magnitude in comparison to those of spontaneous transition for the observed n=17 Stark manifold states at room temperature. And this effect is more remarkable for longer lived states. It, along with the effect of the Stark mixing of l sublevels, will reduce the differences among lifetimes of Stark states in a manifold.

Multistep transitions between Rydberg states of Na induced by blackbody radiation

Enrique J. Galvez, John R. Lewis, B. Chaudhuri +5 more

We report on measurements of the time dependence of the populations of Rydberg states of Na with n=25--33 produced by stepwise excitation or deexcitation from the initially populated state 28s, stimulated by room-temperature blackbody radiation. We also present a theoretical modeling of the experiments, which mainly consists of solving the set of coupled rate equations for all the states involved. The results of the calculations show that for times of the order of the lifetime of 28s the populations of ns and nd states produced via two-step transitions can be up to 30% of the populations of np states. We also find that np states get repopulated via three-step transitions at the 2--12 % level. A comparison between the data and calculations shows good agreement.

CALCULATION OF LIFETIMES OF THE HIGHLY EXCITEDSTARK LEVELS

Meng-Xu Jiang

The Wave functions of Stark levels are derived by using the zero-field ware functions of Rydberg states. Based on this, the rates of spontaneous radiations and stimulated emission produced by blackbody radiation are calculated for the Stark levels of n=15, |ml|=1 manifold of K atom within the I-mixing region. The dependences of the lifetimes of Stark levels on the electric field strength and the environmental temperature around the atoms are discussed.

Lifetimes of Rydberg states of Eu atoms

Hua Jing, Shiwei Ye, Dai Chang-Jian

The radiative lifetimes of the Eu 4f 7 6s n p ( 8 P J or 10 P J ) Rydberg states with J = 5/2 and 11/2 are investigated with a combination of multi-step laser excitation and pulsed electric field ionization, from which their dependence on the effective principal quantum number is observed. The lifetimes of 21 states are reported along with an evaluation of their experimental uncertainty. The influence of blackbody radiation, due to the oven temperature, on the lifetime of the higher- n states is detected. The non-hydrogen behavior of the investigated states is also observed.

Ionization of sodium and rubidium nS , nP , and nD Rydberg atoms by blackbody radiation

Ilya I. Beterov, Denis B. Tretyakov, I. I. Ryabtsev +2 more

Results of theoretical calculations of ionization rates of Rb and Na Rydberg atoms by blackbody radiation (BBR) are presented. Calculations have been performed for $nS$, $nP$, and $nD$ states of Na and Rb, which are commonly used in a variety of experiments, at principal quantum numbers $n=8--65$ and at three ambient temperatures of 77, 300, and $600\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. A peculiarity of our calculations is that we take into account the contributions of BBR-induced redistribution of population between Rydberg states prior to photoionization and field ionization by extraction electric field pulses. The obtained results show that these phenomena affect both the magnitude of measured ionization rates and shapes of their dependences on $n$. The calculated ionization rates are compared with the results of our earlier measurements of BBR-induced ionization rates of Na $nS$ and $nD$ Rydberg states with $n=8--20$ at $300\phantom{\rule{0.3em}{0ex}}\mathrm{K}$. A good agreement for all states except $nS$ with $n>15$ is observed. We also present the useful analytical formulas for the quick estimation of BBR ionization rates of Rydberg atoms.

Stark effect in sodium atomic states highly excited by laser radiation

Valentin M. Apatin, Vladilen S Letokhov, Vyacheslav I. Mishin

Using two-step excitation of the sodium atom by tuned dye lasers, and fluorescence monitoring of the highly excited states, the polarizabilities of the 2D3/2 states with n = 8 and n = 9 were measured. The levels of the n = 9 states were smoothly tuned through 20 cm−1 by increasing the electric field up to 2 kV/cm. The use of the Stark effect as a method of selective stepwise ionization of the atoms by laser radiation is discussed.
