    "abstract": "We have observed self-sustained radial oscillations in a large\nmagneto-optical trap (MOT), containing up to $10^{10}$ Rb$^{85}$ atoms. This\ninstability is due to the competition between the confining force of the MOT\nand the repulsive interaction associated with multiple scattering of light\ninside the cold atomic cloud. A simple analytical model allows us to formulate\na criterion for the instability threshold, in fair agreement with our\nobservations. This criterion shows that large numbers of trapped atoms $N\u003e10^9$\nare required to observe this unstable behavior.",
