摘要：We have performed an experiment at NSCL to study the b -decay of N=Z isotopes 96Cd, 98In and
100Sn using the b -Counting system (BCS) and the Segmented Germanium Array (SeGA). The
nuclei of interest were implanted into a double-sided silicon strip detector and properties from
both implantations and the subsequent b -decays were recorded on an event-by-event basis. The
newly constructed Radio Frequency Fragment Separator (RFFS) was used to reduce the overall
implantation rate due to low momentum tails of less neutron-deficient contaminants. The study of
the doubly magic 100Sn along with its neighbors is essential to understand single-particle structure
and proton-neutron interaction close to the proton drip-line. The measured half-life of 100Sn,
0.55+0.70
0.31 s, is consistent with a previous measurement. The presence of two b−decaying states
in 98In was also confirmed and the improved obtained half-lives are 47(13) ms and 0.66(40) s.
The half-life of 96Cd was measured to be 1.03+0.24
0.21 s.
