Magic and tune-out wavelengths for atomic francium
U. Dammalapati, K. Harada, Y. Sakemi
The frequency dependent polarizabilities of the francium atom are calculated from the available data of energy levels and transition rates. Magic wavelengths for the state insensit…
Compilation of spectroscopic data of Radium (Ra I and Ra II)
U Dammalapati, K. Jungmann, L. Willmann
Energy levels, wavelengths, lifetimes and hyperfine structure constants for the isotopes of the first and second spectra of radium, Ra I and Ra II have been compiled. Wavelengths a…
Lifetime determination of the 5d~F state in barium using trapped atoms
S. De, U. Dammalapati, L. Willmann
Magneto-optically trapped atoms enable the determination of lifetimes of metastable states and higher lying excited states like the state in barium. The sta…
Absolute frequency measurement of the 7s S 7s7p P transition in Ra
B. Santra, U. Dammalapati, A. Groot +2
Transition frequencies were determined for transitions in Ra in an atomic beam and for reference lines in Te molecules in a vapor cell. The absolute frequencies were calibrated…
Isotope Shifts of the D - P Transition in Trapped Short-Lived Ra
G. S. Giri, O. O. Versolato, J. E. van den Berg +13
Laser spectroscopy of short-lived radium isotopes in a linear Paul trap has been performed. The isotope shifts of the D - P transition in $^{209…
Magneto optical trapping of Barium
S. De, U. Dammalapati, K. Jungmann +1
First laser cooling and trapping of the heavy alkaline earth element barium has been achieved based on the strong 6s S - 6s6p P transition for the main cooling.…
