Detection of ultracold ground state molecules with a time-of-flight mass spectrometer [Kurzvortrag]

We have performed photoassociative spectroscopy of cold Cs atoms in a vapor-cell magneto-optical trap, within $10{\mathrm{cm}}^{\ensuremath{-}1}$ below the dissociation limit $6s^{2}S_{1/2}+6p^{2}P_{3/2}$ . Our detection method is based on pulsed-laser photoionization of ${\mathrm{Cs}}_{2}$ molecules, selectively detected through a time-of-flight mass spectrometer. Temporal and spatial analysis of ${\mathrm{Cs}}_{2}^{+}$ ions show for the first time the formation of translationally cold ${\mathrm{Cs}}_{2}$ triplet ground state molecules, at a temperature $T\ensuremath{\sim}300\ensuremath{\mu}\mathrm{K}$.We have performed photoassociative spectroscopy of cold Cs atoms in a vapor-cell magneto-optical trap, within $10{\mathrm{cm}}^{\ensuremath{-}1}$ below the dissociation limit $6s^{2}S_{1/2}+6p^{2}P_{3/2}$.

6s^{2}S_{1/2}+6p^{2}P_{3/2}

. Our detection method is based on pulsed-laser photoionization of

{\mathrm{Cs}}_{2}

molecules, selectively detected through a time-of-flight mass spectrometer. Temporal and spatial analysis of

{\mathrm{Cs}}_{2}^{+}

ions show for the first time the formation of translationally cold
