The 10 even-odd nuclei with an odd number of nucleons, xi = 11:/sup 19/ O, /sup 21/Ne, /sup 21/Na, /sup 23/Na, /sup 25/Mg and xi = 13: /sup 23/Ne, /sup 25/Mg, /sup 25/Al, /sup 27/Al, /sup 27/Si have been studied in the framework of the Bohr-Mottelson and Nilsson models. Two different methods of calculation have been used for the energies and wave functions of positive- and negative-pan-ty states. The ground-state static moments and M1-E2 transition rates have been computed. A minimum number of phenomenological parameter have been used. It has been confirmed that these nuclei (except /sup 19/O) show an equilibrium prolate deformation and can be well accounted for by the model, especially as concerns the positive-parity particle states. Difficulties arise for most of the hole states and negative-parity particle states. Parameter are found to be in the same range for all nuclei. General conclusions on the validity of the model have been discussed in the lower part of the 2s-1d shell. (auth)
