[en] This work represents an update of the previous evaluation of the nuclear data on the A=155 nuclides (2005Re01). The experimental data from reaction and decay studies leading to the following nuclides have been reviewed: ¹⁵⁵La, ¹⁵⁵Ce, ¹⁵⁵Pr, ¹⁵⁵Nd, ¹⁵⁵Pm, ¹⁵⁵Sm, ¹⁵⁵Eu, ¹⁵⁵Gd, ¹⁵⁵Tb, ¹⁵⁵Dy, ¹⁵⁵Ho, ¹⁵⁵Er, ¹⁵⁵Tm, ¹⁵⁵Yb, ¹⁵⁵Lu, ¹⁵⁵Hf, and ¹⁵⁵Ta. These data are presented, together with the adopted level schemes and their properties.

[en] The experimental nuclear structure data available through October 2013 have been reviewed. A summary of information obtained in various reaction and decay experiments is presented, together with adopted level schemes

[en] Nuclear spectroscopic information for experimentally investigated nuclides of mass 141 (Te, I, Xe, Cs, Ba, La, Ce, Pr, Nd, Pm, Sm, Eu, Gd, Tb, Dy, and Ho) has been evaluated. A summary of information obtained in various reaction and decay experiments is presented, together with data tables and adopted level schemes

[en] Precise measurements are being used to test theoretical K-shell internal conversion coefficients (ICCs): in particular, our program has focused on examining whether the atomic K-vacancy formed during the conversion process must be incorporated into the calculations. We report here a measurement on the 65.66-keV, M4 isomeric transition in "1"1"9Sn. Our preliminary result is α_K=1610(27), which confirms the importance of including the vacancy in the ICC calculations

[en] Previously we used relative and absolute efficiency measurements combined with Monte Carlo calculations to define the efficiency of an HPGe gamma-ray detector with 0.2% accuracy from 50 to 1400 keV. This work has been extended to 4.8 MeV with measurements of relative efficiencies from ²⁴Na, ⁵⁶Co, and ⁶⁶Ga sources. The combined results of experiment and calculation yield an efficiency curve up to 3.5 MeV with 0.4% accuracy. Single- and double-escape peak contributions also agree with calculation if positron annihilation-in-flight is incorporated

[en] The 1993 evaluation of A = 97 (1993Ar09) was updated using data available prior to Nov. 19, 2009.

[en] Since 2005, the Cyclotron Institute, Texas A&M, has invested significant effort on ENSDF mass-chain evaluations that was financed by a contract with NNDC-BNL. All resulting evaluation work at Texas A&M has been based on the technical input of an ENSDF evaluator and a scientific adviser. Furthermore, the evolution and emerging status of the center has furnished the opportunity for direct funding through a US DOE grant, and the Cyclotron Institute was approved as a new ENSDF Data Evaluation Center at the International Network of Nuclear Structure and Decay Data Evaluators meeting in 2017.

[en] The 2006 evaluation of A=140 was updated using experimental results published before November 2018 from the various reaction and decay studies leading to the nuclei ¹⁴⁰Sb, ¹⁴⁰Te, ¹⁴⁰I, ¹⁴⁰Xe, ¹⁴⁰Cs, ¹⁴⁰Ba, ¹⁴⁰La, ¹⁴⁰Ce, ¹⁴⁰Pr, ¹⁴⁰Nd, ¹⁴⁰Pm, ¹⁴⁰Sm, ¹⁴⁰Eu, ¹⁴⁰Gd, ¹⁴⁰Tb, ¹⁴⁰Dy, ¹⁴⁰Ho. These data are summarized and presented, together with adopted level schemes and properties.

[en] Since 2005, staff at the Cyclotron Institute, Texas A&M University (TAMU), have carried out ENSDF mass-chain evaluations under contract to NNDC-BNL on the basis of 0.67 FTE. Precise experimental measurements have also been developed and applied to the determination of internal conversion coefficients (ICCs) as a direct form of assistance in the accurate resolution of a wide range of decay schemes and nuclear data evaluations. TAMU was officially recognised as an NSDD Centre in 2017, with expansion to a full FTE devoted to data evaluation (1 FTE). We have continued to contribute to the mass chain evaluation effort by undertaking experimental ICC measurements aimed at consolidating the theoretical approach of calculating the internal conversion coefficients included within the existing ENSDF database. Following on from our series of spectral measurements, Dirac-Fock calculations with the “frozen orbital” approach for inclusion of the atomic vacancy effect on the converted electron were implemented in the BrIcc code. We finalized and published the ninth case in our series of methodical ICC studies (Phys. Rev. C 98 (2018) 054321: 39.8-keV E3 transition of ¹⁰³Rh, a complex case that was studied in terms of both β– and ε decay). Fourteen major publications have now been published on this important topic by the TAMU team. Furthermore, a new set of ICC measurements are currently underway involving the 30.8keV, M4 transition of ^93mNb. The scope of this series of studies is to test the validity of the “frozen orbital” theory over a large domain of Z and A numbers in the chart of the nuclides. We have also contributed indirectly to the nuclear data effort by completing high-quality benchmark measurements (half-lives and branching ratios) by β-γ spectroscopy carried out at the Momentum Achromat Recoil Spectrometer (MARS) at the Cyclotron Institute. Several measurements were completed over this two-year time interval (³⁰S half-life published in Phys. Rev. C 97 (2018) 035501, and ²⁶Si branching ratios, submitted for publication to Phys. Rev. C).

[en] The experimental results published before May 2021 from the various reaction and decay studies leading to nuclides of Z=59 to Z=75, ¹⁶⁰Pr, ¹⁶⁰Nd, ¹⁶⁰Pm, ¹⁶⁰Sm, ¹⁶⁰Eu, ¹⁶⁰Gd, ¹⁶⁰Tb, ¹⁶⁰Dy, ¹⁶⁰Ho, ¹⁶⁰Er, ¹⁶⁰Tm, ¹⁶⁰Yb, ¹⁶⁰Lu, ¹⁶⁰Hf, ¹⁶⁰Ta, ¹⁶⁰W, ¹⁶⁰Re in the A=160 mass chain have been reviewed. These data are summarized and presented, together with adopted level schemes and properties. This work is intended to supersede the previous evaluation of the A=160 nuclides by C.W.Reich (2005Re18), which was published in Nuclear Data Sheets 105, 557 (2005).
