Proton states in193Ir and195Ir populated via the (α) reaction

The nuclear structures of193Ir and195Ir have been studied using the194Pt(t, α) and196Pt(t, α) reactions. Levels up to ∼2MeV in excitation energy were studied with a resolution of ∼13keV (FWHM) and spectroscopic strengths were extracted. The low-lying states in193Ir have been interpreted in terms of both the Nilsson and the rotation-vibration models including Coriolis, particle-vibration and rotation-vibrational couplings. The previously …
