E(level): From least-squares fit to Eγ data. Reduced χ2=0.79, with only two Eγ values deviating slightly, between 2 and 3 σ.
Jπ(level): From γ-ray multipolarities and rotational band structures. Individual arguments for spin and parity assignments are given for rotational bandheads.
T1/2(level): From 231Th β- decay, unless otherwise specified.
M(γ): From conversion electron data in 231Th β- decay, unless otherwise specified.

First identification of 231Pa nuclide is generally accredited to L. Meitner, Zeitschrift fur Elektrochemie und angewandte physikalische Chemie 24, 11-12, 169 (1918), starting with pitchblende without uranium or radium, and isolating both the mother isotope 231Pa and its α-daughter 227Ac. 2013Fr03 mention the identification of 231Pa, as a parent of 227Ac, to O. Hahn and L. Meitner, Z. Physik 19, 208 (1918), where half-life was estimated to be between 1200 y and 180,000 y; and also to an earlier indirect evidence of 231Pa in a paper by F. Soddy and J.α. Cranston, Proc. Roy. Soc. (London), A94, 384 (1918), where half-life was estimated to be >10,000 y. 1931Cu01 evaluation adopted half-life of 32,000 y from 1930Gr01, with the citation of the following earlier references: α.v. Grosse, Ber. Chem. Ges. 61, 233 (1928); Naturwiss. 15, 766 (1927); Nature 120, 621 (1927); O. Hahn and α.v. Grosse, Z. Physik 48, 600 (1928), T1/2=20,200 y; O. Hahn and E. Walling, Naturwiss. 15, 803 (1928); E. Walling, Dissertation (Berlin, 1928), T1/2=20.760 y. Most current half-life measurement of 32,570 y 130 is reported by 2020Je01, a result from collaboration of independent measurements at six different laboratories
Application of 231Pa as described in n.E. Holden et al., Pure Appl. Chem. 90, 1833 (2018), "231Pa is a natural radiogenic isotope produced by α decay of 235U to 231Th, followed by β emission to form 231Pa. Although its behavior in the environment as a transient member of the U-series decay chain may be complex, measurements and modeling of 231Pa in relation to the isotopes of uranium and thorium have been used in a variety of geochronologic applications on time scales of 103 to 105 years. Studies include movement of water masses and particles in the oceans, rates of magma melting and movement beneath volcanoes, and ages of carbonate mineral deposits, including corals, in relation to climate change ".

Theoretical calculations: consult the NSR database (www.nndc.bnl.gov/nsr) for 115 primary references, 97 dealing with half-lives of α and cluster decays and other aspects of radioactive decays, and 19 with nuclear structure calculations. Some of these references are listed in ’document’ records in this dataset, which can be accessed through on-line ENSDF database at www.nndc.bnl.gov/ensdf/
Levels: 231Pa presents K=1/2 rotational bands with opposite parity and decoupling parameters with very close absolute values, as well as enhanced E1 γ-ray transitions between parity-doublet band levels. These are typical features of nuclei with large stable octupole deformations. However, 231Pa has a small β3 deformation parameter of 0.02. Consequently, the characteristic features mentioned before have been explained by using large octupole-phonon components in the low-lying states. Extensive calculations of level energies and B(E1) reduced transition probabilities using the quasiparticle-plus-phonon model (QPM) have produced acceptable agreement between theory and experiment (1996Le01).
Levels: The even-parity states in 231Pa are members of rotational bands that are strongly mixed by the Coriolis interaction. This mixing affects level energies as well as α, β, and γ-ray transition probabilities. Comprehensive Coriolis calculations have explained distortions in rotational band level spacings (which includes the unusual inversion of the 84- (5/2+), 102- (3/2+), and 101-keV (7/2+) states in the 3/2[651] rotational band). These calculations also produced values for γ-ray, β- (231Th β- decay), and α-particle (235Np α decay) transition probabilities between these states (1975Ho14, 1973Br12). The agreement between experimental results and calculated values have confirmed the rotational band assignments presented here. Band assignments are from Coulomb excitation, (p,2nγ), (α,t), and 231U ε decay (2003Wu03,1996Le01,1975Er01,1973Br12)
Gammas: Gamma-ray transition probabilities are from Coulomb excitation, unless otherwise indicated
