Abstract: Experimental data for the excited states in the deformed nucleus 230Th studied in the (p, t) reaction are analyzed. Sequences of the states are selected which can be treated as rotational bands and as multiplets of excitations. Experimental data are compared with the interacting boson model (IBM) and the quasiparticle-phonon model (QPM) calculations.
Keywords: collective bands, moments of inertia, interacting boson model, quasiparticle-phonon model.
