This Review presents electron affinities of atoms and structures of atomic negative ions. The negative ion properties of many elements in the main groups of the Periodic Table were well known in the late 20th century. However, our knowledge of the atomic negative ions of transitional elements, lanthanides, and actinides was completely lacking or largely rather qualitative at that time. Substantial progress both on experimental and theoretical sides in this subject has happened during the last two decades. New developments in the experimental methods that yield accurate electron affinities are described in this Review. Based on the previous reviews, a survey of the electron affinity toward the completion of the Periodic Table is presented. A set of atomic electron affinities and energy levels of atomic anions is recommended.

In this work, new thermodynamic models for refrigerant mixtures are provided for the binary pairs R-1234yf/134a, R-1234yf/1234ze(E), and R-134a/1234ze(E) based on new reference measurements of speed of sound, density, and bubble-point pressures. Fitting the very accurate liquid-phase speed of sound and density data reproduces the bubble-point pressures to within close to their uncertainty, yielding deviations in density less than 0.1% and speed of sound deviations less than 1% (and less than 0.1% for R-1234yf/134a). Models are also presented for the binary pairs R-125/1234yf, R-1234ze(E)/227ea, and R-1234yf/152a based solely on bubble-point measurements.

The International Association for the Properties of Water and Steam has adopted new formulations for the thermodynamic and transport properties of heavy water. This manuscript describes the development of a formulation for the thermal conductivity of heavy water that was adopted as an international standard in 2021. It is consistent with the equation of state adopted in 2017, revised slightly in 2018, and is valid for fluid states up to 825 K and 250 MPa with uncertainties ranging from 1.5% to 6% depending on the state point. Comparisons with experimental data and with an earlier thermal-conductivity formulation are presented. The 2021 formulation accounts for the critical enhancement of the thermal conductivity, which was not incorporated in the previous formulation. Furthermore, in the zero-density limit, the 2021 formulation is based on thermal conductivity values at temperatures from 250 to 2500 K obtained from the kinetic theory of polyatomic gases. In addition, the 2021 formulation is applicable in a larger range of pressures than the previous formulation.

Atomic spectroscopy and atomic physics papers represent a significant part of publications in Journal of Physical and Chemical Reference Data (JPCRD). Critical compilations of spectroscopic data, accurate calculations of collisional parameters, and bibliography on spectral line profiles and shifts provided much needed information for plasma physics, astrophysics, lithography, fusion research, and other fields of science. We present a brief overview of the atomic physics research published in JPCRD over its first 50 years.
