We study K+Ar collisions by laser excitation of the collision pair in a differential scattering experiment. The relative population of the K(4p)2P fine-structure sublevels reflects the nonadiabatic coupling in the convergence region of the interactio

Experimental differential cross sections for the optical collision process K(4s)2S + Ar + hν → K(4p)2P + Ar are reported. The characteristic interference structures are used to determine the repulsive parts of the KAr X2Σ and B2Σ potential curve

We have investigated the laser excitation of CaAr collision pairs in a molecular beam experiment with differential detection. The metastable Ca(4s3d) 1 D state is populated by a collision-assisted transition. Measurements of differential cross-sectio

Every measurement of the population in an uncorrelated ensemble of two-level systems is limited by what is known as the quantum projection noise limit. Here, we present quantum projection noise limited performance of a Ramsey type interferometer usin

In this work, we examine a system for coherent transfer of atoms into a Bose-Einstein condensate. We utilize two spatially separate Bose-Einstein condensates in different hyperfine ground states held in the same dc magnetic trap. By means of a pulsed

We study the properties of an atom laser beam derived from a Bose-Einstein condensate using three different outcouplers, one based on multi-state radio frequency transitions and two others based on Raman transitions capable of imparting momentum to t

We report on the observation and characterisation of an inelastic loss feature in collisions between ultracold Rb-85 |F=2, m_F=-2> atoms at a magnetic field of 220 G. Our apparatus creates ultracold Rb-85 clouds by sympathetic cooling with a Rb-87 re

We present results on a Raman laser-system that resonantly drives a closed two-photon transition between two levels in different hyperfine ground states of 87Rb. The coupler is based on a novel optical design for producing two phase-coherent optical

A pulsed atom laser derived from a Bose-Einstein condensate is used to probe a second target condensate. The target condensate scatters the incident atom laser pulse. From the spatial distribution of scattered atoms, one can infer important propertie

We present the experimental realization of a pumped atom laser. We demonstrate the pumping through measurements of the source and laser-mode atom numbers, making a rate equation study of the pumping process.
