$β$-Decay Half-Lives of Neutron-Rich Sulfur to Potassium: Evolution of the $N=32$ and 34 Subshell Closures below Calcium

Author(s): Q. B. Zeng et al. The half-lives of 24 isotopes ranging from sulfur to potassium were measured using the ZeroDegree Advanced Decay Station at the Radioactive Isotope Beam Factory, including six of the most neutron-rich—$^{47}\mathrm{S}$, $^{48,49}\mathrm{Cl}$, $^{51,52}\mathrm{Ar}$, $^{55}\mathrm{K}$—for the first ti… [Phys.
