PROMOTION OF THE SCISSORS MOTION BY CONSISTENT INTERACTIONS

A relationship is found between the quantized isovector rotor and the microscopic RPA formalism. The scissors restoring force is obtained fr om a sum-rule approach. It is not influenced significantly by symmetry -restoring interactions, derived consistently from the deformed potent ial. The resulting neutron-proton interaction generates a scissors res toring force, which almost coincides with that extracted by the relati ve angular momentum from the deformed mean field alone. Such consisten t interactions do not favour much orbital M1 strength at high energy a nd the scissors mode fragments mainly over the low-lying orbital 1+ ex citations.
