$\beta -$decay studies of nuclides in the $^{100}$Sn region at NSCL
ORAL
Abstract
$\beta -$decay nuclides in the immediate neighborhood of $^{100}$Sn, were studied at NSCL using the $\beta $-Counting system (BCS) and the Segmented Germanium Array (SeGA). The nuclei of interest were implanted into the BCS double-sided silicon strip detector and properties from both implantations and the subsequent $\beta $-decays were recorded on an event-by-event basis, allowing for the direct observation of the half-lives and the $\beta $-delayed proton emission branching ratios. The BCS also contains a stack of Si detectors and a Ge planar detector downstream of the implantation detector to measure the total energy of the emitted beta particles, and hence the $\beta $-decay end-point energy. The properties of those nuclei are not only relevant for rp-process calculations but also are essential to understand the structure of the single particle states far from the line of stability, providing stringent tests of nuclear models in this region.
