Abstract

The deformation driving $ν i_{13 / 2}$ [660]1/2 structure has been identified for the first time in $^{131} Nd .$ It is the lightest Nd $(Z = 60)$ isotope in which a band based on this intruder orbital has been reported. A crossing between the [411]1/2 band and the [660]1/2 sequence takes place near $ħ ω \approx 0.34$ MeV with a large interaction strength $(| V |_{\max} = 47$ keV). Thus, a smooth transition from the normal to the highly deformed minimum is established in $^{131} Nd .$
