The population of the high-spin states in 140Nd was investigated using the reaction 96Zr(48Ca,4n). The results
from two experiments, one with the EUROBALL array and one with the JUROGAM II + RITU + GREAT setup
employing the recoil decay tagging technique, have been combined to develop a very detailed level scheme for
140Nd. Twelve bands of quadrupole transitions and eleven bands of dipole transitions were identified and their
connections to low-lying states were established. Calculations using the cranked Nilsson-Strutinsky and the tilted
axis cranking models were used to interpret the observed structures. The overall good agreement between the
experimental results and the calculations assuming a triaxial shape of the nucleus strongly support the existence
of a stable triaxial shape at high spins in this mass region.
