Lifetimes of the low-lying 72− states in 113, 115Cd

The half-lives of the $\text{7}\text{2}{}^{\mathrm{?}}$ states at 522.6 and 393.9 keV in ¹¹³Cd and ¹¹⁵Cd have been determined to be 0.322±0.012 and 0.75± 0.03 ns, respectively. Values of the $\text{B(}\text{E}\text{2,}\text{7}\text{2}{}^{\mathrm{?}}\text{→}\text{11}\text{2}{}^{\mathrm{?}}$) and the energy difference in odd Cd (A = 113–119) are compared with those in neighbouring even Cd. The level properties are interpreted in the framework of the triaxial rotor model.
