     The theoretical study of the odd-mass nuclei 123La at low lying excitation energy has been realised by the quasiparticle-phonon plus rotor coupling (QPRM). The two effects of recoil and coriolis force have been included with the hypothesis of a symmetric rotational motion. The deformed average field of Nilsson is renormalized by taking account of the terms  and   coming from the g-quadrupole force.
