The beta-decay half-life of 48 130 Cd82 and its importance for astrophysicalr-process scenarios
The s-decay half-life of130Cd has been measured and its importance as N=82 ‘waiting-point’ nucleus for astrophysical rapid neutron capture (r−) process scenarios is discussed.
Origin of the odd-even staggering in theA?80 solarR-abundance peak
In contrast to the conventional picture, the r-process yields in the A≃80 abundance peak exhibit a pronounced odd-even staggering. It is proposed that this behaviour may be due to strong β-delayed neutron branching from a few odd-mass isotopes located in or close to the r-process path.
