In the search for the fully aligned 27− state in 140Nd predicted by cranked Nilsson-Strutinsky calculations, new
close-to-spherical high-spin states have been discovered. Both the close-to-spherical and the triaxial calculated
states are in good agreement with the experimental results, supporting the existence of shape coexistence up to
very high spins. Shell-model calculations using a newly developed effective interaction for the 50 N ,Z 82
mass region are in good agreement with the observed spherical states. The comparison between the experimental
and calculated level energies allowed the relative energy to be established between several proton and neutron
orbitals at high energy and spins.
