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…
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.…
Isotope shifts of 6s5d D-states in neutral Barium
U. Dammalapati, S. De, K. Jungmann +1
Laser spectroscopy of the low lying P and D states in atomic barium has been performed. This work contributes substantially to the development of an effective laser cooling…
Production and trapping of radioactive atoms at the TRI\muP facility
E. Traykov, U. Dammalapati, S. De +12
The structures for the TRIP facility have been completed and commissioned. At the facility radioactive nuclides are produced to study fundamental interactions and symmetries. An…
Development of a thermal ionizer as ion catcher
E. Traykov, U. Dammalapati, S. De +12
An effective ion catcher is an important part of a radioactive beam facility that is based on in-flight production. The catcher stops fast radioactive products and emits them as si…
Coherent Dark Resonances in Atomic Barium
U. Dammalapati, S. De, K. Jungmann +1
The observation of dark-resonances in the two-electron atom barium and their influence on optical cooling is reported. In heavy alkali earth atoms, i.e. barium or radium, optical c…
