Reply to “Comment on ‘Measurement of the lifetimes of S and D states below n=31 using cold Rydberg gas”’

Abstract

In response to the preceding Comment, we present important experimental information on our $S$, $P$, and $D$ Rydberg lifetime measurements for $^{85}\mathrm{Rb}$ using a sample of cold Rydberg atoms. We analyze and discuss the implications of blackbody radiation transfer on our results. We also discuss the limitation of the theory compared with our results.

Comment on “Measurement of the lifetimes of S and D states below n=31 using cold Rydberg gas”

Duncan Tate

A recent paper by [Nascimento et al., Phys. Rev. A 74, 054501 (2006)], and a previous paper from the same group [de Oliveira et al., Phys. Rev. A 65 031401(R) (2002)], report measurements of Rydberg lifetimes in rubidium in the range $27\ensuremath{\le}n\ensuremath{\le}44$. In this Comment, we point out one apparent flaw of experimental technique in these papers that may lead to systematic errors in the results. We also clarify a point of theoretical interpretation used in these papers which suggests that the agreement between experiment and theory may not be as good as it seems.

Measurement of the lifetimes of S and D states below n=31 using cold Rydberg gas

Valter Aragão do Nascimento, L. L. Caliri, A. L. de Oliveira +2 more

In this paper we have extended our previous work [de Oliveira et al., Phys. Rev. A 65, 031401 (2002)] by measuring the $S$ and $D$ Rydberg lifetimes for $^{85}\mathrm{Rb}$ for principal quantum number between $n=26$ and 31 using a sample of cold Rydberg atoms. This range is limited by the amplitude of the electric field that we can generate in our present setup.

All-optical measurement of Rydberg-state lifetimes

Markus Mack, Jens Grimmel, Florian Karlewski +3 more

We have developed an all-optical method for measuring the lifetimes of $nS$ and $nD$ Rydberg states and demonstrate its capabilities with measurements on a dilute cloud of ultracold $^{87}\mathrm{Rb}$ atoms in a cryogenic environment. The method is based on the time-resolved observation of resonant light absorption by ground-state atoms and selective transfer of Rydberg atoms into the ground state at varying delay times in order to reconstruct Rydberg decay curves. Our measurements of the $^{87}\mathrm{Rb}$ $30{S}_{1/2}$ state indicate an increase of the lifetime at lowered environment temperatures, as expected due to decreased blackbody radiation. For the $38{D}_{5/2}$ state with an attractive dipole-dipole interaction, ionization and lifetime reduction due to collisional effects are observed.

Measurement of Rydberg-state lifetimes using cold trapped atoms

A. L. de Oliveira, M. W. Mancini, Vanderlei Salvador Bagnato +1 more

In this paper, we demonstrate the use of a cold trapped sample of neutral atoms to perform high-precision measurement of the lifetime for a sequence of Rydberg states of ${}^{85}\mathrm{Rb}.$ States of principal quantum number lying between $n=31$ and $n=45$ are produced and their lifetimes measured using field ionization. Experimental results are compared with existing theories. This is an important demonstration concerning the possibilities of high-precision spectroscopy in the time domain using cold atomic samples.

Lifetimes of alkali-metal—atom Rydberg states

Constantine E. Theodosiou

We report a comprehensive set of calculations of the lifetimes of Rydberg states in alkali-metal atoms, using realistic potentials to represent the atomic core. The effects due to core polarizability, spin-orbit interaction, and blackbody radiation are explicitly included. A complete cross reference listing of all available experimental lifetimes is also attempted. The results compare well with experiment for all principal quantum numbers $n$ examined and should provide guidance for future experimental investigations. The relation of the present approach to other works is discussed.
