The decay of the two new isotopes ${}_{}{}^{112}{}_{}{}^{}\mathrm{Te}$ ($T_{\frac{1}{2}}=2.0\mathrm{}\pm 0.2$ min) and ${}_{}{}^{113}{}_{}{}^{}\mathrm{Te}$ ($T_{\frac{1}{2}}=1.6\mathrm{}\pm 0.2$ min) is investigated, together with the decay of the ${}_{}{}^{114}{}_{}{}^{}\mathrm{Te}$ ($T_{\frac{1}{2}}=15.2\mathrm{}\pm 0.7$ min) and the two isomers in ${}_{}{}^{115}{}_{}{}^{}\mathrm{Te}$ ($T_{\frac{1}{2}}=5.7\mathrm{}\pm 0.2 min \mathrm{and} 6.7\pm 0.4 min$). Decay schemes are proposed and compared to previously available data and theoretical calculations. Some systematic trends are discussed.

RADIOACTIVITY ${}_{}{}^{112,113,114}{}_{}{}^{}\mathrm{Te}$, ${}_{}{}^{115}{}_{}{}^{}\mathrm{Te}_{}^{g+m}{}_{}{}^{}$ [from ${}_{}{}^{\mathrm{}\left(112\right),\left(114\right)\mathrm{}}{}_{}{}^{}\mathrm{Sn}({}_{}{}^3{}_{}{}^{}\mathrm{He},xn)$)]; measured $T_{\frac{1}{2}}$, $E_{\gamma }$, $\gamma \gamma$-coin, $\gamma \gamma \Delta t$; deduced $log\mathrm{ft}$; ${}_{}{}^{112,113,114,115}{}_{}{}^{}\mathrm{Sb}$ deduced levels, $J$, $\pi$. Isotope separated sources.
