Abstract:

We present direct measurements of the overall trap loss rate and the fine structure changing collision rate for ultracold cesium atom confined in a magneto-optical trap over an intensity range of 5 mW/cm2 to 200 mW/cm2. This set of simultaneous measurements allows the accurate extraction and separation of the fine structure changing rate and the radiative escape rate as these two processes compete with one another to determine the overall trap loss rate.
