Multiple triaxial bands in Nd-138
(2015) In Physical Review C (Nuclear Physics) 91(2).- Abstract
- High-spin states in Nd-138 were investigated by using the Ca-48 + Zr-94 reaction and gamma-ray coincidences were acquired with the GASP spectrometer. A rich level scheme was developed including 14 new bands of quadrupole transitions at very high spins. Linking transitions connecting 11 high-spin bands to low-energy states have been observed. Calculations based on the cranked Nilsson-Strutinsky formalism have been used to assign configurations to the observed bands. The main result of these calculations is that all 14 bands exhibit a stable triaxial deformation up to the highest observed spins, giving strong support to the existence of a triaxial minimum with normal deformation and positive asymmetry parameter in nuclei with a few holes in...
