A MICROSCOPIC CALCULATION OF THE ISOVECTOR MAGNETIC MODE IN DEFORMED NUCLEI

A microscopic calculation has been carried out based on the random phase approximation (RPA) with deformed Woods-Saxon basis for k^π = 1⁺ rnode in deformed nuclei. The calculation shows that the orbital part of the magnetic dipole ( Ml ) operator plays a dominant role in exciting M₁ (k^π = 1⁺ ) mode. A fragmentation of the strength in the energy range of 2-4MeV has been found.
