In the mass regions near single-closed shell configurations such as Tl(Z = 81), Sb(Z = 51), In(Z = 49) and N = 81, N = 83 isotones; deformed Nilsson orbitals can give rise to minima in the total potential energy of the nucleus. Thus low-lying, deformed states can occur whereas the ground state in these nuclei is spherical. Comparison with the existing experimental data is made in all cases.
