Two superdeformed bands have been observed in the nucleus {sup 145}Sm in an experiment performed with the Gammasphere multidetector array. One of these bands demonstrates a sudden rise in its dynamic moment of inertia at low frequency which may be related to the interaction between N=6 Nilsson orbitals at the Fermi surface. The other band has a moment of inertia identical to the yrast band of {sup 149}Gd, making it the fourth case in the A{approx_equal}150 mass region of identical bands in nuclei differing by an {alpha} particle. {copyright} {ital 1998} {ital The American Physical Society}
