Beta-decay Studies of r-process Nuclei Using the Advanced Implantation Detector Array (AIDA)
Lead Research Organisation:
University of Edinburgh
Department Name: Sch of Physics and Astronomy
Abstract
AIDA is one of the latest silicon implantation detector arrays and is used at fragmentation facilities to study decay processes of radioactive nuclei. The r-process is believed to be responsible in producing over half of the elements heavier than iron and as such is a key process in understanding the chemical evolution of the universe. To better understand the path that the r-process takes more experimental data is needed to be used in models. This experimental data includes beta-decay half-lives and beta-dilated neutron emission probabilities for nuclei far from stability. These are nuclei with short half-lives and as such requires the use of instrumentation with high precision and sensitivity such as AIDA.
