Abstract: Reactions involving short-lived radioactive nuclei play an important role in explosive stellar nucleo-synthesis. Studying these reactions in the laboratory is complicated due to the low beam intensities, the poor energy resolution, and contaminations from other stable ion species.

In this talk, I will give a brief history of the radioactive in-flight beam program at ATLAS and how beams and detectors for experiments with these short-lived nuclei were developed. Results from a few  experiments involving some of the ~30 radioactive beams produced so far will be presented.
