Abstract

Creating around half of all isotopes heavier than iron, the r-process is an important process in nucleosynthesis and the chemical evolution of the Universe. However, the lack of experimental nuclear data for unstable isotopes is one important obstacle for a complete understanding of the r-process. Key parameters in r-process calculations include the β-decay half-lives and β-delayed neutron emission probabilities Pn for neutron-rich isotopes along the r-process path. The Advanced Implantation Detector Array (AIDA) represents the latest generation of silicon implantation detectors for use at fragmentation beam facilities and will improve the precision and sensitivity of experiments, allowing the study of new and rare nuclear decay processes.
