Neutron captures and the rare earth peak

Published Proceedings of Science, NIC-XI 273 (2010)

The rr-process is an important component of heavy element nucleosynthesis. We study the sensitivity of the rr-process abundance pattern to neutron capture rates along the rare earth peak (A150A\sim150 to A180A\sim180). We determine the type of conditions which produce a rare earth peak consistent with the solar rr-process data. We identify important neutron capture rates among the rare earth isotopes and show how these rates influence specific sections of the abundance pattern.
