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…
Gamow-Teller Unit Cross Sections for (t,3He) and (3He,t) Reactions
G. Perdikakis, R. G. T. Zegers, Sam M. Austin +16
The proportionality between differential cross sections at vanishing linear momentum transfer and Gamow-Teller transition strength, expressed in terms of the \textit{unit cross sec…
Gamow-Teller transitions to 64-Cu measured using the 64-Zn(t,3-He) reaction
G. W. Hitt, R. G. T. Zegers, Sam M. Austin +9
The 64-Zn(t,3-He) reaction has been studied using a secondary triton beam of 115 MeV/nucleon to extract the Gamow-Teller transition-strength distribution to 64-Cu. The results were…
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…
Gamow-Teller strengths in 24Na using the 24Mg(t,3He) reaction at 115 AMeV
M. E. Howard, R. G. T. Zegers, Sam M. Austin +16
Gamow-Teller transitions from 24Mg to 24Na were studied via the (t,3He) reaction at 115 AMeV using a secondary triton beam produced via fast fragmentation of 150 AMeV 16O ions. Com…
