Nuclear Reactions in the Big Bang

Reactions of interest to Big Bang Nucleosynthesis have been studied at RIKEN, a laboratory northwest of Tokyo, Japan. These reactions involve short lived nuclides, e.g. 8Li or 16C, so require use of the RIKEN Projectile Fragment Separator, (RIPS), shown in the clickable image . In some cases, e.g. that of 16C, the decay properties were observed, whereas in the case of 8Li, reactions involving them were studied using this facility. Involved in this project are Prof. Richard Boyd and his postdoc Gerry Raimann of the Nuclear Physics Experimental group. For a list of our recent publications, click here. And here are a few more pictures from our most recent trip to Tokyo.

High Temperature Stellar Nucleosynthesis

Nuclei that are important to high temperature stellar nucleosynthesis have been studied using the on-line mass separator of the radioactive beam facility at GSI, near Darmstadt, Germany. These processes proceed through the most proton rich nuclides that exist. The lifetimes and decay modes of those nuclei are thus important to the predicitions of the nuclei synthesized in these conditions; we have studied several of them, including 98Cd, 99Ag, and 100Pd, nuclei that are far beyond the proton rich side of stability. Involved in this project are Prof. Richard Boyd and his postdoc Gerry Raimann of the Nuclear Physics Experimental group. For a list of our recent publications, click here.
