Title: Intense slow beams of bosonic potassium isotopes

Abstract

We report on an experimental realization of a two-dimensional magneto-optical trap (2D-MOT) that allows the generation of cold atomic beams of {sup 39}K and {sup 41}K bosonic potassium isotopes. The high measured fluxes up to 1.0x10{sup 11} atoms/s and low atomic velocities around 33 m/s are well suited for a fast and reliable three-dimensional magneto-optical trap loading, a basilar feature for new generation experiments on Bose-Einstein condensation of dilute atomic samples. We also present a simple multilevel theoretical model for the calculation of the light-induced force acting on an atom moving in a MOT. The model gives a good agreement between predicted and measured flux and velocity values for our 2D-MOT.
