Abstract
We present direct measurements of the overall trap loss rate and the fine s tructure changing collision rate for ultracold cesium atom confined in a ma gneto-optical trap over an intensity range of 5 mW/cm(2) to 200 mW/cm(2). T his set of simultaneous measurements allows the accurate extraction and sep aration of the fine structure changing rate and the radiative escape rate a s these two processes compete with one another to determine the overall tra p loss rate.
