✦ Synopsis

A contextual study of low-lying magnetic and electric dipole excitations is carried out for several deformed odd-mass nuclei using a separable Hamiltonian within the quasiparticle-phonon nuclear model. The M 1 and E 1 core states are composed of one plus two-phonon components, those having a different multipolarity are simply one-phonon states. All phonons are computed microscopically in the random-phase approximation. The resulting M1 and E1 spectra are compared with the available experimental data.
