Abstract：
Total-Routhian-Surface calculations have been performed to investigate the deformation and alignment properties of the No isotopes. It is found that normal deformed and superdeformed states in these nuclei can coexist at low excitation energies. In neutron-deficient No isotopes, the superdeformed shapes can even
become the ground states. Moreover, we plotted the kinematic moments
of inertia of the No isotopes, which follow very nicely available experimental data. It is noted that, as the rotational frequency increases, alignments develop at hω=0.2－0.3MeV. Our calculations show that the occupation of the νj_15/2 orbital plays an important role in the alignments of the No isotopes.
