Jade: a radioactive decay network and its application to the treatment of isomers in the r process
ORAL
Abstract
The rapid neutron capture process, or r process, is expected to produce some of the heaviest elements observed to exist in nature. In the immediate aftermath of the r process in astrophysical environments, the nuclei produced are extremely neutron-rich and, therefore, undergo a long period of radioactive decay proceeding through a broad swath of the chart of nuclides, the effect of which can drive a range of observables associated with these events. In this work, we discuss Jade, a radioactive decay network which can include both ground and isomeric nuclear states in modeling the radioactive decay of r process ejecta.
