Penning ionization reactions in merged beams with precisely controlled collision energies have been shown to accurately probe quantum mechanical effects in reactive collisions. A complete microscopic understanding of the reaction is, however, faced with two major challenges-the highly excited character of the reaction's entrance channel and the limited precision of even the best state-of-the-art ab initio potential energy surfaces. Here, we suggest photoassociation spectroscopy as a tool to…

Imaging Recoil Ions from Optical Collisions between Ultracold, Metastable Neon Isotopes.

An experimental scheme that combines the well-established method of velocity-map imaging with a cold trapped metastable neon target is presented, enabling opportunities for precision measurements in nuclear decays of cold, trapped, short-lived radioactive isotopes.

Ultrafast Creation of Overlapping Rydberg Electrons in an Atomic BEC and Mott-Insulator Lattice.

An array of ultracold atoms in an optical lattice excited with a coherent ultrashort laser pulse to a state where single-electron wave functions spatially overlap signals the actual creation of electronic states with overlapping wave functions.

Intrabeam Scattering for Ultracold Collisions.

A method to probe cold and ultracold chemistry in a single molecular beam by implementing a dual-slit chopper that can separately fix the velocities of the two species at the interaction region to establish the relative velocity is demonstrated.

Single-Source, Collinear Merged-Beam Experiment for the Study of Reactive Neutral-Neutral Collisions.

We present two methods for studying reactive collisions between two atomic or molecular species: a collinear merged-beam method, in which two gas pulses from a single supersonic beam source are

Quantum control of molecular rotation

The angular momentum of molecules, or, equivalently, their rotation in three-dimensional space, is ideally suited for quantum control. Molecular angular momentum is naturally quantized, time

Rovibrational cooling of photoassociated Rb285 molecules at millikelvin temperature

We investigate theoretically the rovibrational cooling of the $^{85}\mathrm{Rb}_{2}$ molecule resulting from the photoassociation of $^{85}\mathrm{Rb}_{2}$ atoms at millikelvin temperature. At



Observation of the isotope effect in sub-kelvin reactions.

It is demonstrated that measurements of a single isotope are insufficient to constrain ab initio calculations, making the kinetic isotope effect in the cold regime necessary to remove ambiguity among possible potential energy surfaces.

Ultracold photoassociation spectroscopy: Long-range molecules and atomic scattering

Photoassociation is the process in which two colliding atoms absorb a photon to form an excited molecule. The development of laser-cooling techniques for producing gases at ultracold !!1 mK"

Observation of Resonances in Penning Ionization Reactions at Sub-Kelvin Temperatures in Merged Beams

The realization of merged neutral supersonic beams and the manifestation of clear nonclassical effects in the resulting reactions are reported, which should be widely applicable to many canonical chemical reactions.

Enhancing photoassociation rates by nonresonant-light control of shape resonances

Photoassociation, assembling molecules from atoms using laser light, is limited by the low density of atom pairs at sufficiently short interatomic separations. Here, we show that non-resonant light

Low-temperature collisions between neutral molecules in merged molecular beams.

The method is described and results on the Ne((3)P2)+NH3 Penning ionization are presented, which enables the study of chemical processes at very low temperatures without the need to prepare slow molecules in the laboratory frame of reference.

Giant helium dimers produced by photoassociation of ultracold metastable atoms.

Good agreement is reported between the spectroscopic measurements and the calculations of the five bound states belonging to a 0(+)(u) purely long-range potential well of metastable helium atoms in a magnetically trapped, ultracold cloud.

Sub-Kelvin Collision Temperatures in Merged Neutral Beams by Correlation in Phase-Space

Three vibrational series are observed by photoassociation spectroscopy of cold He(2 3S) atoms and a possible mechanism to explain the observed increase of the Penning ionization rate is discussed.
