Q(β-)=570.3 keV 20S(n)= 6528 keV 8S(p)= 5246.3 keV 11Q(α)= 4375 keV 12
Reference: 2017WA10

  A  233Th β- decay (21.83 M)  B  237Np α decay (2.144×106 Y)
  C  232Th(3He,d),(α,t)  D  232Pa(n,γ),(n,n):Resonances
  E  234U(t,α),(pol t,α)  F  232Th(209Bi,208PBG)

General Comments:

See 232Pa(n,γ),(n,n):resonances dataset for 28 neutron resonances in the energy range of 0.33 eV to 20.63 eV.

Other reaction:

1998Er01, 1995Er02, 1993Er01: 232Th(d,nF),E=7.5-15.6 MeV; measured fission fragment σ(θ) using single-crystal targets, and blocking technique. Deduced deduced mean fission lifetimes vs excitation energy, and level densities in second potential well.

Theoretical studies: consult the NSR database at www.nndc.bnl.gov for 16 references dealing with theoretical structure calculations, and seven related to decay modes and half-lives

Levels: Uncertain levels at 219 and 283 keV deduced from questionable α transitions are not included here.

Levels: Level energies for various configurations were calculated by 1974Mo18 and 1975Iv06.

Q-value: S(2n)=12077.6 17, S(2p)=12851 13 (2017Wa10)

E(level): From least-squares fit to Eγ values, assuming 0.3 keV uncertainty for Eγ when not stated. For levels populated only in the particle-transfer reactions, averages were taken of available data

Jπ(level): For low-spin states, see 232Th(3He,d),(α,t) and 234U(t,α),(pol t,α) datasets for methods of determining Jπ and Nilsson assignments based on vector analyzing power measurements in (pol t,α), and comparison of experimental and theoretical cross sections for Nilsson orbital assignments. Assignments for high-spin (J>11/2) states are based on probable rotational bands and yrast population pattern in heavy-ion reactions. Additional Jπ arguments are given for individual levels.

Additional Gamma Comments:

E(level)E(gamma)Comments
   103.656    17.40E(γ): poor fit, level-energy difference=17.18 2
   169.169   162.505I(γ): unweighted average from β- and α decays
   212.348   108.7I(γ): from α decay, γ not observed in β- decay
   155.242I(γ): from α decay. Other: 79 10 from β- decay
   212.32I(γ): from α decay. Other: 224 21 from β- decay is in severe disagreement. The intensities of the 117.7 and 212.3 γ rays given in 2008De31 measurement seem problematic. Evaluators recommend γ-branching ratios for the 212-keV level from α decay, as the level is more strongly populated in this decay as compared to that in β- decay.
