The field of cold molecules has become an important source of new insight in fundamental
chemistry and molecular physics. High-resolution spectroscopy benefits from translationally …

Over the past decade, and particularly the past five years, a quiet revolution has been
building at the border between atomic physics and experimental quantum chemistry. The …

We report on the electrostatic trapping of neutral SrF molecules. The molecules are captured
from a cryogenic buffer-gas beam source into the moving traps of a 4.5-m-long traveling …

We present a method which delivers a continuous, high-density beam of slow and internally
cold polar molecules. In our source, warm molecules are first cooled by collisions with a …

The recent development of a range of techniques for producing cold atoms and molecules at
very low translational temperatures T≤ 1 K has provided the opportunity to investigate …

A detailed description of a merged beam apparatus for the study of low energy molecular
scattering is given. This review is intended to guide any scientist who plans to construct a …

Molecules can be used to test fundamental physics. Such tests often require cold molecules
for detailed spectroscopic analysis. Cooling internal degrees of freedom provides a high …

We present a study of Sisyphus cooling of molecules: The scattering of a single photon
removes a substantial amount of the molecular kinetic energy and an optical pumping step …

Rate constants for chemical reactions of laser-cooled Ca+ ions and neutral polar molecules
(⁠ CH 3 F⁠, CH 2 F 2⁠, or CH 3 Cl⁠) have been measured at low collision energies (⟨ E …

We report experiments in which a slow Rydberg positronium (Ps) beam was produced by
velocity selection using a curved electrostatic quadrupole guide. Ps atoms in Rydberg-Stark …
