Abstract. Nuclear levels in 23~ have been investigatedin the fl decay of 23~ the a3~ pnT) reaction and the 232Th(p, t) reaction. The K'=0~ -, 2 + , and 2 3 bands with band heads at 635, 781, and 1010 keV were observed up to the 8 +, 9 +, and 7 + levels, respectively. A second excited 0 + level was identified at 1297 keV which might be interpreted as the usual fl shape-oscillation. The branching ratios of the E2 transitions from the 0~-, 2~, and 2+ bands are explained in the framework of the rotational model by taking into account the coupling of these bands with the ground-state band, and the coupling between the 0~ + and 2~ + band. A strong enhancement of E2 transitions from the 2 + to the 0 + band reported earlier is not confirmed. For the octupole vibrations with K ~ = 0-, 1 -, and 2-the E 1 branching ratios are analyzed in terms of the Coriolis coupling of these bands. An almost complete experimental set of E1 transition moments from these negative-parity bands to the 0 § 0~, and 2~-bands was g obtained. It is suggested that octupole correlations might be important in explaining these E 1 moments.

“…Several close-lying levels were identified at 1757. 9 + [7]. Different γ-lines were used in the identification of the levels at 1757.9 and 1758.24 keV: 741.9, 1361.4, 1430.0 keV for the first one and 1571.52 and 1700.59 keV for the latter.…”

“…The tritons were analyzed with the Q3D magnetic spectrograph and then detected in a focal plane detector. The focal plane detector is a multiwire proportional chamber with readout of a cathode foil structure for position determination and dE/E particle identification [9,10]. The acceptance of the spectrograph was 11 msr, except for the most forward angle of 5…”

The excitation spectra in the deformed nucleus 228 Th have been studied by means of the (p,t) reaction, using the Q3D spectrograph facility at the Munich Tandem accelerator. The angular distributions of tritons were measured for about 110 excitations seen in the triton spectra up to 2.5 MeV. Firm 0 + assignments are made for 17 excited states by comparison of experimental angular distributions with the calculated ones using the CHUCK3 code. Assignments up to spin 6 + are made for other states. Sequences of states are selected which can be treated as rotational bands and as multiplets of excitations. Moments of inertia have been derived from these sequences, whose values may be considered as evidence of the two-phonon nature of most 0 + excitations. Experimental data are compared with interacting boson model (IBM) and quasiparticle-phonon model (QPM) calculations and with experimental data for 229 Pa.

“…The position in the focal plane was measured by a light-ion, focal-plane detector of 1.8 m active length using two single-wire proportional counters surrounded by two etched cathode foils [20]. Using that detector with the spectrograph, a linewidth of #3 keV has been observed for elastic scattering of 20 MeV deuterons.…”
