Low-lying states of 119Sb studied from the decay of 119mTe

The electron-capture decay of ^119mTe was investigated with an iron-free π√2 β-spectrometer and Ge(Li) detectors. The investigation includes subshell-ratio and γγ angular correlation measurements in addition to conversion-coefficient and γγ coincidence measurements. The level scheme of ¹¹⁹Sb was proposed, which incorporates 13 excited states and 34 transitions. The spin-parities were determined as follows: $\text{270.53}\text{keV}\text{7}\text{2}{}^{\mathrm{+}}\text{, 970.91}\text{9}\text{2}{}^{\mathrm{+}}\text{, 1048.42}\text{7}\text{2}{}^{\mathrm{+}}\text{, 1212.75}\text{9}\text{2}{}^{\mathrm{+}}\text{, 1249.78}\text{9}\text{2}{}^{\mathrm{+}}\text{, 1366.32}\text{11}\text{2}{}^{\mathrm{?}}\text{, 1407.21}\text{11}\text{2}{}^{\mathrm{+}}\text{, 2129.83}\text{9}\text{2}{}^{\mathrm{?}}\text{, 2226.02}\text{11}\text{2}{}^{\mathrm{?}}\text{, 2278.87}\text{13}\text{2}{}^{\mathrm{?}}\text{, 2283.78}\text{9}\text{2}{}^{\mathrm{?}}\text{, 2360.22}\text{9}\text{2}{}^{\mathrm{?}}\text{and}\text{2379.61 (}\text{9}\text{2}\text{,}\text{13}\text{2}\text{)}{}^{\mathrm{?}}$. The level structure of ₅₁¹¹⁹Sb₆₈ is discussed in comparison with a core-particle coupling calculation. All the levels seen in the decay of ^119mTe are correlated with the theoretical levels except for the 970.91 $\text{9}\text{2}$⁺ level, which has been recently identified as a deformed state.
