Abstract
The effect of a neutron skin on the collective scissors mode in very n eutron-rich nuclei is investigated. The algebraic approach is used to show that the development of a neutron skin can give rise to an additi onal low-lying mode involving out-of-phase motion of the skin neutrons against the remaining nucleons of the core. This ''soft'' scissors mo de represents the analogue of the soft dipole mode already postulated to occur in such nuclei. (C) 1997 Elsevier Science B.V.
