description

The decays of three new neutron-rich nuclides $^{111}\mathrm{Tc}$, $^{113}\mathrm{Ru}$, and $^{113}\mathrm{Rh}$ have been observed at an on-line isotope separator facility. In addition, the beta decays of several other n-rich isotopes with Ag100 have been studied for the first time. The new half-lives reported in this work include: $^{111}\mathrm{Tc}$ [${T}_{1/2}$=0.30(3) s], $^{111}\mathrm{Ru}$ [2.12(7) s], $^{112}\mathrm{Ru}$ [1.75(7) s], $^{113}\mathrm{Ru}$ [0.80(10) s], $^{113}\mathrm{Rh}$ [2.72(22) s], and $^{118}\mathrm{Pd}$ [2.24(17) s]. In general, these results support the microscopic theoretical half-life predictions below Z=50.
