High spin collective excitations in 101Ru

The energy level structure of ¹⁰¹Ru was studied using the reactions ¹⁰⁰Mo(α, 3n) ¹⁰¹Ru and ¹⁰⁰Mo( ³He, 2n) ¹⁰¹Ru. Excitation functions, γγ coincidences and γ-ray angular distributions were measured. Three ΔI = 2 cascades proceeding to a {5}/{2}⁺, {7}/{2}⁺ and {11}/{2}^- state were observed. A decay scheme is presented showing energies up to 5849 keV and spins up to {35}/{2}. The bands are discussed within the framework of the Nilsson model with Coriolis coupling in which the recoil effect has been properly introduced.
