Adding an extra nucleon having a definite K-value to an axially symmetrical even-even core generates a breaking of the time-reversal symmetry. Within the Skyrme-Hartree-Fock approach the effects of the time-odd mean-field terms resulting from the presence of non-vanishing current and spin-vector densities are investigated. In this preliminary study, pairing correlations are not taken into account. The associated removal of the Kramers degeneracy is interpreted in terms of diamagnetic/paramagnetic types of polarization of the even-even core in the field of an odd particle. This general approach is illustrated here by calculations in the region of light fragments of heavy (e.g. actinide) nuclei.< Réduire
