Precision Spectroscopy of Atomic Hydrogen and Variations of Fundamental Constants
M. Fischer, N. Kolachevsky, M. Zimmermann +14
In 2003 we have measured the absolute frequency of the two-photon transition in atomic hydrogen. We observed a variati…

Optimizing the production of metastable calcium atoms in a magneto-optical trap
Jan Gruenert, Andreas Hemmerich
We investigate the production of long lived metastable (3P2, n=4) calcium atoms in a magneto-optical trap operating on the 1S0 to 1P1 transition at 423 nm. For excited 1P1-atoms a…

Ultracold Metastable Calcium Ensembles, a Medium for Matter Wave Amplification ?
J. Gruenert, G. Quehl, V. Elman +1
We propose an experimental implementation of matter wave amplification by optical pumping (MAO) with metastable calcium atoms. First experimental results indicate that pumping rate…
