Quasiparticle--phonon model of the nucleus II. The phonon space and giant Elambda resonances in deformed nuclei
The results are given of calculations of single-phonon states in even--even deformed nuclei, which form a basis in the quasiparticle--phonon model of the nucleus. It is shown that the calculations of the single-phonon states with multipolarity lambda=1, 2, and 3 have a unique result, while those with multipolarity lambda> or =4 contain a certain arbitrariness associated with the choice of the constants of the multipole--multipole interactions. The parameters of the calculations in deformed nuclei in the regions 150< or =A< or =190 and 226< or =A<260 are systematized. In the single-phonon approximation, a fairly good description is obtained of the positions and widths of giant dipole, quadrupole, and octupole resonances. The results of calculations of Elambda resonances of high multipolarity are given.
