Abstract
Vibrational states in doubly even nuclei have been calculated in the framework of the Quasiparticle—Phonon Nuclear Model (QPNM) (Soloviev, 1987; 1989) with inclusion of ph and pp isoscalar and isovector multipole and ph spin—multipole magnetic interactions with wave functions consisting of one— two— and in some cases of three— RPA phonon components. A new phonon operator has been introduced by Soloviev (1991) consisting of the electric and magnetic parts. Among numerous results obtained in our calculations we have chosen for this report the following two: The contribution of doubly gamma vibrational components to the wave function of the first K π = 4+ state in 168Er and the M2 and M3 strength distribution in 164Dy and 168Er.
