Coexisting structures inRu105

New positive-parity states, having a bandlike structure, were observed in $^{105}\mathrm{Ru}$. The nucleus was produced in an induced fission reaction, and the prompt $\ensuremath{\gamma}$-rays, emitted from the fragments, were detected by the EUROBALL III multidetector array. The partial scheme of excited $^{105}\mathrm{Ru}$ levels is analyzed within the triaxial-rotor-plus-particle approach.
