Anisotropy of atom–atom repulsions
Journal of Computational Chemistry, 1994AbstractWe describe investigations of the short‐range repulsion part of the intermolecular potential using a test particle approach. This approach provides an economical method of constructing reasonably accurate model repulsion potentials and demonstrates the importance of anisotropy in describing the short‐range repulsion.

Atomic manipulation using a scanning tunneling microscope (STM) tip enables the construction of quantum structures on an atom-by-atom basis, as well as the investigation of the electronic and dynamical properties of individual atoms on a one-atom-at-a-time basis.

AbstractMit Hilfe der Spitze eines Rastertunnelmikroskops wird ein einzelnes metallfreies Phthalocyanin‐Molekül in ein Silber‐Phthalocynanin auf einer Obefläche umgewandelt. Die Reaktionsschritte erfolgen Atom für Atom. Jedes Zwischenprodukt kann mit Hilfe von rastertunnelmikroskopischen Aufnahmen analysiert werden.

ATOMIC CLOCKS AND COLD ATOM SCATTERING
Laser Spectroscopy, 2002We demonstrate a Rb fountain clock which has a small cold collision shift that is cancelled by detuning the microwave cavity. To further enhance the stability and accuracy, we are currently developing a new state detection technique that directly measures population differences and are juggling atoms in the fountain. Fountain clocks also enable a novel

Abstract Atomic collisions are normal1y termed elastic or inelastic. The former lead simply to momentt1m transfer between the collision partners, or equivalently to a change in the direction of their motions; the latter lead also to a simultaneous transfer of energy between internal motion and translation.

Atom optics, guided atoms, and atom interferometry
2005Publisher Summary This chapter discusses the applicability of micro-optical elements for the preparation and manipulation of atomic samples. This development is in many respects complementary to the use of miniaturized magnetic traps, so called atom chips.

Although Be− ions have been produced by several means (described below), it is generally agreed that a stable Be− ion, i.e., an anionic state below the ground state of neutral Be, does not exist. Rather, Be− is believed to be metastable.

Atom Interferometry, Atom Optics and the Atom Laser
2001Abstract : Our goal is to pursue atom interferometry and advances of the atom laser using Bose-Einstein condensates. Condensates will be moved from a vacuum chamber where they were produced into a science chamber where a great variety of experiments can be carried out without the severe limitations imposed by the cooling and trapping techniques applied
