1. Intensity dependence for trap loss rate in a magneto-optical trap of strontium
We have measured the collisional loss rate for cold strontium atoms held in a magneto-optical trap as a function of light intensity in the regime of low intensity (2-6 mW/cm²). The results confirm our recently proposed model, where we showed that the sudden increase of loss rate at low intensities does not depend on hyperfine structure changing collision on

2. Estudo de taxas de perdas em sistemas heteronucleares / Trap loss in a two-species Rb-Cs magneto-optical trap
In this work, we had investigated the heteronuclear trap loss rate in a two-species Rb-Cs magneto-optical trap. The experimental results suggest that radiative escape is the main collisional process responsible for heteronuclear losses. An addapted Gallagher - Pritchard model is compared with the data. The model is very sensitive to the trap depth, which dep

3. Colisões Inelásticas Frias em Amostras Heteronucleares obtidas em Armadilhas Magneto-Ópticas. / Cold inelastic collisions in two species magneto optical traps.
We report the results of the trap-Ioss collisional rates observed in a mixed species magneto-optical trapo These are the first systematic studies about the collisionalloss channels due to heteronuclear interactions between two cold atomic sampIes in aMOr. We have used two different combinations: Na-Rb and K -Rb. lt was observed that the rates are strongly af
