Description

Two excited superdeformed bands in 149Gd have been observed in γ-ray spectroscopy. Based on the behavior of the dynamical moments of inertia, we assign one band to a neutron excitation and the other to a proton excitation. The proton-excited-band γ-ray energies are nearly identical to those already known in 150Tb. In addition, two new members of the 149Gd yrast cascade have been observed, extending the band to spin 135/2ℎ. The results are discussed in terms of high-N intruder orbitals in the cranked-shell model
