Algebraic treatment of multi-step excitation processes in collective nuclei: (II). Electromagnetic excitation of collective nuclear states

Multi-step collective quadrupole excitations in nuclei are described using an algebraic method which does not require a coupled-channel calculation. Adiabatic effects are discussed. Applications to the axially-symmetric deformed rotor, anharmonic quadrupole vibrator, and γ-soft rotor, as well as to transitional nuclei, are presented using the consistent-Q formulation of the interacting boson model.
