Аннотация

Lifetimes of the first ${4}^{+}$ and ${6}^{+}$ states in ${}^{104}\mathrm{Mo}$ and ${}^{106}\mathrm{Mo}$ have been measured using the recoil distance method following spontaneous fission of ${}^{252}\mathrm{Cf}.$ The experiment was performed at the 88-inch cyclotron of the Lawrence Berkeley National Laboratory employing the Gammasphere array and the New Yale Plunger Device. Reduced transition probabilities in the ground state band of ${}^{104}\mathrm{Mo}$ are compared with predictions of the critical point symmetry X(5) for phase transitional nuclei between rotational and vibrational shape. While known level energies of ${}^{104}\mathrm{Mo}$ are in good agreement with the X(5) predictions, the analysis of the measured $B(E2)$ values favors a rotor interpretation.
