Coulomb excitation ofTe125

The properties of the low-lying levels of ${}_{}{}^{125}{}_{}{}^{}\mathrm{Te}$ were investigated by the Coulomb excitation process which was effected by bombarding a thick natural tellurium target with 9.5- and 10.5-MeV $\alpha$ particles and a thick target of isotopically enriched ${}_{}{}^{125}{}_{}{}^{}\mathrm{Te}$ (95%) with 45-MeV ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ ions. Levels at 443.58, 463.39, 671.42, and 729.30 MeV were Coulomb excited and the reduced upward transition probabilities $B\left(E2\mathrm{}\uparrow \right)$ ($e^2 {\mathrm{b}}^2$) extracted from the data were: 0.186 ± 0.005, 0.158 ± 0.005, 0.130 ± 0.004, and 0.0059 ± 0.0008. Angular distribution measurements were performed with 42-MeV ${}_{}{}^{16}{}_{}{}^{}\mathrm{O}$ ions. The following results were obtained for the $\gamma$ rays deexciting the 443.58- ($\frac{3}{2^{+}}$) keV level: $\delta \mathrm{}\left(408.10\right)=+0.41\mathrm{}\left(5\right)\mathrm{} or +1.35\mathrm{}\left(12\right)\mathrm{}$, $\delta \mathrm{}\left(443.58\right)=+0.14\mathrm{}\left(4\right)\mathrm{} or -2.4\mathrm{}\left(3\right)\mathrm{}$.
