A compilation of wavelengths and energy levels for the spectrum of neutral rubidium (Rb I)

Abstract

We are presenting a complete list of wavelengths for all classified lines of Rb I. The data are based mainly on the observations and analysis of this spectrum by many authors. The tabulated data include 615 observed lines in the spectral range 103– 27,905 A ̊ , classified as transitions among 22 even-parity and 414 odd-parity levels. Vacuum wavelengths are given for all the lines, and wavelengths in air are also included for the region above 2000 A ̊ . We also present the results of the doppler-free two-photon absorption spectrum for the transition n 2S←5 2S and n 2D←5 2S of atomic rubidium.
