LOW-LYING MAGNETIC AND ELECTRIC DIPOLE TRANSITIONS IN ODD-MASS DEFORMED NUCLEI - A MICROSCOPIC APPROACH

摘要

A contextual study of low-lying magnetic and electric dipole excitations is carried out for several deformed odd-mass nuclei using a separable Hamiltonian within the quasiparticle-phonon nuclear model. The M1 and E1 core states are composed of one plus two-phonon components, those having a different multipolarity are simply one-phonon states. All phonons are computed microscopically in the random-phase approximation, The resulting M1 and E1 spectra are compared with the available experimental data. [References: 51]
