The principles and applications of the quasimolecular treatment of optical and radiative
collisions are discussed. Main attention is focused on the uniform approximation to the …

Excitation of Atoms and Broadening of Spectral Lines povides a survey of elementary
processes and mechanisms. It presents useful and relatively simple methods of …

We report a preliminary value for the zero magnetic field Na 2 S (f= 1, m=− 1)+ Na 2 S (f= 1,
m=− 1) scattering length, a 1,− 1. This parameter describes the low-energy elastic two-body …

This paper examines two collisional mechanisms by which cold alkali-metal atoms can
escape from a neutral-atom trap, due to collison of excited-and ground-state atoms. One is …

We form ultracold Na 2 molecules by single-photon photoassociation of a Bose-Einstein
condensate, measuring the photoassociation rate, linewidth, and light shift of the J= 1, v …

Publisher Summary This chapter presents the theory of collisions among laser-cooled
atoms. Laser cooling techniques offer many new opportunities for science and technology …

Sodium vapor, in the density range 10 13 to 5× 10 14 cm− 3, was excited by a cw dye laser,
tuned 20-150 GHz from either the D 1 or D 2 resonance line. We observed a three-peak …

We present a method for determining the depth of an atomic or molecular trap of any type.
This method relies on a measurement of the trap loss rate induced by collisions with …

The density dependence of the line width and resonance frequency of the cesium D 1 line is
studied with Doppler-free frequency modulated selective reflection spectroscopy. The …

We investigate the radiative collision rate in an ultracold, optically trapped cesium gas near
a magnetically tunable Feshbach resonance. The radiative trap loss is suppressed by a …
