Predicting reaction observables from back-scattering measurements in low-energy heavy-ion collisions
The physics of low-energy nuclear reactions is crucial for understanding the chemical evolution in the Universe and is at the core of the science programmes in new-generation rare-isotope beam facilities.
For a better understanding of this physics, the establishment of the relationships among various observables is useful. I will report on a method for extracting the reaction and capture cross sections as well as the elastic-scattering differential cross sections from back-scattering measurements of elastic and quasi-elastic excitation functions [1,2]. The method has been tested againts coupled reaction channels calculations, and will be illustrated with various heavy-ion systems.
