Neutron capture on 130Sn during r-process freeze-out
J. Beun, J. C. Blackmon, W. R. Hix +3
We examine the role of neutron capture on 130Sn during r-process freeze-out in the neutrino-driven wind environment of the core-collapse supernova. We find that the global r-proces…
Neutron Capture Rates near A=130 which Effect a Global Change to the r-Process Abundance Distribution
R. Surman, J. Beun, G. C. McLaughlin +1
We investigate the impact of neutron capture rates near the A=130 peak on the -process abundance pattern. We show that these capture rates can alter the abundances of individual…
Fission Cycling in a Supernova r-process
J. Beun, G. C. McLaughlin, R. Surman +1
Recent halo star abundance observations exhibit an important feature of consequence to the r-process: the presence of a main r-process between the second and third peaks which is c…
Neutrinos, Fission Cycling, and the r-process
J. Beun, G. C. McLaughlin, R. Surman +1
It has long been suggested that fission cycling may play an important role in the r-process. Fission cycling can only occur in a very neutron rich environment. In traditional calcu…
Fission Cycling in Supernova Nucleosynthesis: Active-Sterile Neutrino Oscillations
J. Beun, G. C. McLaughlin, R. Surman +1
We investigate nucleosynthesis in the supernovae post-core bounce neutrino-driven wind environment in the presence of active-sterile neutrino transformation. We consider active-ste…
