Lifetimes of excited states in triaxially deformed ¹⁰⁷Tc and ^{109, 111, 113}Rh

NUCLEAR REACTIONS ⁹B(²³⁸U, F), E=6.2 MeV/nucleon; measured reaction products. ¹⁰⁷Tc, ^109,111,113Rh; measured prompt Eγ, Iγ, γγ-coin using EXOGAM Ge detector array, (ion)γ-coin; deduced T_1/2, positive-parity yrast bands using Recoil-Distance Doppler Shift (RDDS) method; calculated yrast bands states T_1/2 using triaxial particle-rotor method; deduced configuration for the strongest positive-parity band in ¹⁰⁷Tc, indicated gradual increase of triaxial deformation with atomic number Z, reaching almost maximum triaxiality for neutron-rich Rh nuclei. T_1/2 compared to data.
