General Comments:

Wave functions and energies for the K=2+ γ vibrational, K=0-, 1-, 2-, 3- octupole vibrational states were calculated by 1964So02 and 1975Iv03. See also 1969Bl13, 1970Ne08, 1974Be69, 1976Iv01, 1988Ot02 for calculated energies of these collective states. 1964So02 calculated also two-quasiparticle state energies. K=2 γ- and K=0 β-band energies were calculated by 1978To13, 1984Ba59; and K=0-, K=0+ band energies by 1990TrZY. See 1989Eg02 for calculated level energies and systematics of 1- states. For calculations of two-phonon state energy, see 1981So05, 1988Le14. For calculated positive parity, K=0 and K=2 band spectra and comparison with experiments, see 1989Br21.

The B(E2) and B(E3) values for excitation of the 2+ and 3- members of quadrupole and octupole band, respectively, were calculated by 1975Iv03, 1970Ne08, 1988Ot02. B(E2) was also calculated by 1981So11, 1982Gu05 and 1990TrZY. The B(E3) and B(E1) values for the excitation of 3-, 1- levels of K=0, K=1 bands, respectively, were calculated by 1977Ba45. See also 1984Ba59 and 1989Ch07 for calculated B(E3) values.

For calculations and discussions on reduced transition probabilities of gammas deexciting the octupole vibrational states, see for example, 1965So04, 1971Ku25, 1972Va24, 1987Na05, 1987Na27, 1989Eg02, 1990TrZY, 1990Na30. For calculated reduced E2 transition probabilities of gammas from the β and the γ vibrational band to the g.s. band, see 1965Be40, 1986Go07, 1989Br21.

In order to explain the observed (p,t) cross section to the 0+ state at 635 keV, various formalisms were applied; (t,p) and (p,t) strengths, E0 and E2 reduced transition probabilities were calculated by 1972Va20, 1973Im02, 1976Ra12. Hindrance factor of α transition to this 0+ state was calculated by 1969Cr05, 1972Ci02.

For proposed structures of low-lying 0+ states and for discussions, see for example, 1969Cr05, 1972Ci02, 1972Ma15, 1972Va20, 1973Im02, 1976Ra12, 1976Iv04, 1990TrZY.

For calculated equilibrium quadrupole and hexadecapole deformation parameters, see 1970Ga12, 1974Br36, 1982Du16, 1982Le19, 1982Li01, 1983Ro14, 1984Eg01, 1984Na22, for example.

For deformation parameters deduced from Coulomb excitation, see 1973Be44 and 1977Mi11. For deformation parameter deduced from the ratio of (p,t) spectroscopic factors for g.s. and the first 0+ state, see 1979Ab10.

1985Na07 studied the influence of octupole deformation on high-spin properties of nuclear spectra. See also 1986Sc18 for discussions on stable octupole deformations in neighboring thorium isotopes that may be deduced from displacement energy of the positive- and the negative-parity bands, and from enhanced E1 transitions connecting those bands.

Changes in nuclear shapes were studied by 1984Va24 as dependence on spin.

For systematics of the proton- and neutron-pairing interaction strengths estimated from empirical odd-even mass differences, see 1989Pi03.

For calculations of nuclear potential at large deformation, see for example, 1971Pa20, 1971Oh07, 1972Ma11, 1987Be42. For calculations of fission-barrier energies, see 1972Ma11, 1979Sh01, 1980Ku14. For experimentally deduced energies, see 1988Bl03 (triple-humped fission barrier) and 1974Ba28 (double-humped barrier). Nuclear properties (energy, ε (2,3,4,5,6), moment of inertia) at the third minimum were studied by 1987Be42.

Level energies of the shape isomers in two wells were deduced by 1988Bl03 from fission probability measurements in 229Th(d,pF) reaction. Level energy of the shape isomer in first well was calculated by 1972Ma11.

Deformations, quadrupole and hexadecapole moments, moment of inertia of the expected first shape isomer were calculated by 1973So01, 1974Br36, 1978Po01.

E(level): Deduced by evaluators from a least squares fit to adopted γ-ray energies, unless otherwise specified.

Jπ(level): Spin/parity assignments are based on rotational and band structures, on γ-ray multipolarities, on log ft values from 230Ac β- decay and 230Pa ε decay, and on hindrance factors from 234U α decay. For levels populated only in 234Th(p,t), spin/parity assignments are based on angular distribution of scattered tritons. Some additional specific arguments are given for individual levels.

M(γ): From ce measurements in 230Pa ε decay. Multipolarities in square brackets are from level scheme; they are included for transition-rate calculations when needed.
