Proton particle states in the region around 13250Sn82

The decay of ¹³³Sn leading to levels in ¹³³₅₁Sb₈₂, which has one proton outside the closed shell, has been observed at the OSIRIS isotope separator on-line facility. The half-life is 1.47±0.04 sec and the $\text{d}{}_{\mathrm{<mtext>5</mtext><mtext>2</mtext>}}$. level is found at an excitation of 963 keV. The decay of $\text{18±1}\text{sec}{}^{135}\text{Te}$ to one-particle and three-particle levels in ^135₅₃I₈₂ has also been studied.
