Quasiparticle--phonon model of the nucleus. IV. Fragmentation of single-phonon and two-quasiparticle states in spherical nuclei
The review gives a systematic exposition of the quasiparticle--phonon model of the nucleus as applied to even--even spherical nuclei when the state wave functions are represented as superpositions of single-phonon and two-phonon components. Exact and approximate systems of equations are obtained for determining the energies and coefficients of the wave functions, and expressions are derived for various strength functions. The results are given of calculations of the characteristics of electric giant multipole resonances, neutron and radiative strength functions, and the fragmentation of two-quasiparticle states. Comparison with experiments shows that a good description of the listed characteristics is achieved.
