Beta-decay half-lives and beta-delayed neutron emission probabilities of nuclei in the region below A=110, relevant for the r-process
J. Pereira, S. Hennrich, A. Aprahamian +21
Measurements of the beta-decay properties of r-process nuclei below A=110 have been completed at the National Superconducting Cyclotron Laboratory, at Michigan State University. Be…
Beta-decay of nuclei around Se-90. Search for signatures of a N=56 sub-shell closure relevant the r-process
M. Quinn, A. Aprahamian, J. Pereira +26
Nuclear structure plays a significant role on the rapid neutron capture process (r-process) since shapes evolve with the emergence of shells and sub-shells. There was some indicati…
Time-of-flight mass measurements for nuclear processes in neutron star crusts
A. Estrade, M. Matos, H. Schatz +23
The location of electron capture heat sources in the crust of accreting neutron stars depends on the masses of extremely neutron-rich nuclei. We present first results from a new im…
Beta decay studies of r-process nuclei at the National Superconducting Cyclotron Laboratory
J. Pereira, A. Aprahamian, O. Arndt +22
The impact of nuclear physics on astrophysical r-process models is discussed, emphasizing the importance of beta-decay properties of neutron-rich nuclei. Several r-process motivate…
The neutron long counter NERO for studies of beta-delayed neutron emission in the r-process
J. Pereira, P. Hosmer, G. Lorusso +23
The neutron long counter NERO was built at the National Superconducting Cyclotron Laboratory (NSCL), Michigan State University, for measuring beta-delayed neutron-emission probabil…
Nucleosynthesis in the Early Galaxy
F. Montes, T. C. Beers, J. Cowan +8
Recent observations of r-process-enriched metal-poor star abundances reveal a non-uniform abundance pattern for elements . Based on non-correlation trends between elementa…
R-process Experimental Campaign at the National Superconducting Cyclotron Laboratory
J. Pereira, S. Hennrich, M. Quinn +19
A JINA/VISTARS r-process campaign was completed at the A1900 Fragment Separator of the National Superconducting Cyclotron Laboratory in the fall of 2005. The purpose of the campaig…
