Evaluated nuclear structure and decay data for all nuclei with mass number A=206 (206Pt, 206Au, 206Hg, 206Tl, 206Pb, 206Bi, 206Po, 206At, 206Rn, 206Fr, 206Ra and 206Ac), are presented. All available experimental data are compiled and evaluated, and best values for level and γ-ray energies, quantum numbers, lifetimes, γ-ray intensities and transition probabilities, as well as other nuclear properties, are recommended. Inconsistencies and discrepancies that exist in the literature are discussed. A number of computer codes (https://www-nds.iaea.org/public/ensdf_pgm/) developed by members of the NSDD network were used during the evaluation process. This work supersedes the earlier evaluation by F.G. Kondev (2008Ko21), published in Nuclear Data Sheets 109, 1527 (2008).

Experimental nuclear structure and decay data are evaluated for 9 known nuclides of mass number A=32 (F, Ne, Na, Mg, Al, Si, P, S, Cl, Ar). Detailed evaluated information is presented for each reaction and decay and recommended values combining all available data are provided for all spectroscopic properties of each level, γ transition, and decay radiation. Effort has been made to search for 32F (2019Ah07) with no success, suggesting unbound towards neutron emission. Information for excited states in 32Ne, 32Na and 32Ar are very limited, and spin-parity of 32Na remains undetermined experimentally; only a few excited states have been identified in 32Al, and the decay schemes of 32Mg β− decay to 32Al and 32Al to 32Si are still incomplete; 32Mg, 32P and 32S have been studied via various reactions and decays, with 32S one of the most extensively studied nuclei in the sd-shell. This work supersedes earlier full evaluations of A=32 by 2011Ou01, 1998En04, 1990En08 and 1978En02.

The experimental results published before Aug 2022 from the various reaction and decay studies leading to nuclides of Z=56 to Z=72, 154Ba, 154La, 154Ce, 154Pr, 154Nd, 154Pm, 154Sm, 154Eu, 154Gd, 154Tb, 154Dy, 154Ho, 154Er, 154Tm, 154Yb, 154Lu, 154Hf, in the A=154 mass chain have been reviewed. These data are collected and presented in decay or reaction datasets, together with Adopted Levels and gammas datasets that are the most extensive collections of nuclear structure data for each nuclide. This work is intended to supersede the previous evaluation of the A=154 nuclides by C.W. Reich (2009Re14), which was published in Nuclear Data Sheets 110, 2257 (2009).

Experimental structure and decay data are evaluated for eight known nuclides of mass number A=33 (Na, Mg, Al, Si, P, S, Cl, Ar). Experimental studies for the identification of other three nuclides: 33F, 33Ne and 33K by 2019Ah07, 2007Ba71, and 1986La17, respectively, have not met with success, and values of S(2n) for 33F, S(n) for 33Ne and S(p) for 33K from systematics (2021Wa16) and theoretical calculations (2019Mo01) suggest that these nuclei are likely unbound towards particle emission. Detailed evaluated level properties and related information are presented and recommended spectroscopic parameters are provided, combining all the data from various reactions and decays. Information for excited states in 33Na is limited and the spin of 33Al g.s. still has not been determined unambiguously. The radioactive decay schemes of 33Na, 33Mg, 33Al and 33Si remain incomplete. The 33S nuclide is the most extensively studied from many different reactions and decays, followed by 33Cl and 33P. This work supersedes earlier full evaluations of A=33 published by 2011Ch49, 1990En08 (also 1998En04 update) and 1978En02.

Nuclear structure data pertaining to all nuclei with mass number A=81 (Ni, Cu, Zn, Ga, Ge, As, Se, Br, Kr, Rb, Sr, Y, Zr, Nb, Mo) have been compiled and evaluated and incorporated into the ENSDF data file. This evaluation for A=81 supersedes the previous one, 2008Ba34.
Highlights of this evaluation are the following:
From fragmentation reaction studies of 238U beam at 345 MeV/nucleon on a Be target, one count has been assigned to 81Ni in 2017Su15, which is assumed to correspond to the g.s. activity of 81Ni and the Adopted Levels dataset has been proposed.
The absolute Iγ determined in 1982De36 (81Y ε decay (70.4 s)) from total Iγ/total β+ recoils implies a 97% g.s. branch (from (5/2+) to 1/2−) in the 81Y ε decay, which is discrepant compared to the g.s. feeding of <2.6 in this evaluation. The absolute Iγ of 1982De36 was not considered in the previous evaluation (2008Ba34), same in this one as well. The reason for this major discrepancy is not understood. The decay scheme normalization is consequently tentative.
81Zr g.s. half-life measurements have been reported from (113, 175, and 230γ(t)) and decay curves for β events correlated with 81Zr implantations. No additional data are available. A 81Zr ε decay (5.3 s) dataset has been created based on the data from the Adopted Levels, Gammas of 81Y.
