A summary is presented for the current models used to calculate energy levels in deformed odd-mass nuclei. The Nilsson scheme is discussed. In this scheme the spheroidal nucleus is assumed to have axial symmetry and the internal motion of the odd nucleon in the nonspherical field of the core is assumed to be separable from collective motions. The case where the two types of excitations, rotational and single particle. interact through a spin-orbital coupling of the odd nucleon with the nonspherical field is also considered. This is discussed for both axially asymmetric nuclei. For nonaxial nuclei the gamma deformation parameter is allowed to be different from zero. The scheme is used for calculating energy levels in the mass region from 17 to 39. Diagrams are shown comparing calculated and experimental energy levels, spins and parities for P/sup 29/, Si/sup 29/, and P/sup 31/. It was concluded that because of the coupling between single particle and collective motions the angular momentum number K and its projection on the symmetry axis OMEGA cannot characterize exactly the properties of an excited level. It is necessary to take into account the complex interaction between rotational and single particle states of the same parity. Such calculations can lead to not only the spins and energies of excited levels but their wave functions as well. (TTT)
