Abstract

The excitation spectra in the deformed nucleus ²³⁰Th were studied by means of the (p,t ) reaction, using the Q3D spectrograph facility at theMunich Tandem accelerator. The angular distributions of tritons aremeasured for about 200 excitations seen in the triton spectra up to 3.3 MeV. Firm 0 ⁺ assignments are made for 16 excited states by comparison of experimental angular distributions with the calculated ones using the CHUCK code. Additional assignments are possible, with assignments for four states relatively firm and another four tentative. Assignments up to spin 6⁺ are made for other states. Sequences of the states are selected that can be treated as rotational bands and as multiplets of excitations. Experimental data are compared with interacting boson model (IBM) and quasiparticle-phonon model (QPM) calculations.
