Contribution
It presents new experimental data on 105Ru's excited states and applies a triaxial-rotor-plus-particle model for analysis, advancing understanding of its nuclear structure.
Findings
Identification of new positive-parity states
Observation of band-like structures in 105Ru
Application of triaxial-rotor-plus-particle model
Abstract
New positive-parity states, having a band-like structure, were observed in 105Ru. The nucleus was produced in induced fission reaction and the prompt gamma-rays, emitted from the fragments, were detected by the EUROBALL III multi-detector array. The partial scheme of excited 105Ru levels is analyzed within the Triaxial-Rotor-plus-Particle approach.
