Benchmark experiment with iron slab by Time-of-flight technique at CIAE [PDF]
EPJ Web of Conferences, 2020 In order to validate the evaluated nuclear data, leakage spectra in the range of 0.8 to 15 MeV from samples were measured by time-of-flight (TOF) technique using a D-T neutron source.

Atomic Data Assessment with PyNeb [PDF]
Atoms, 2020 PyNeb is a Python package widely used to model emission lines in gaseous nebulae. We take advantage of its object-oriented architecture, class methods, and historical atomic database to structure a practical environment for atomic data assessment.

Atomic data for the Gaia-ESO Survey [PDF]
, 2020 We describe the atomic and molecular data that were used for the abundance analyses of FGK-type stars carried out within the Gaia-ESO Survey. We present an unprecedented effort to create a homogeneous line list, which was used by several abundance ...

Analysis of atomic-clock data to constrain variations of fundamental constants [PDF]
New Journal of Physics, 2023 We present a new framework to study the time variation of fundamental constants in a model-independent way. Model independence implies more free parameters than assumed in previous studies.

Introduction of a C6D6 detector system on the Back-n of CSNS [PDF]
EPJ Web of Conferences, 2020 Radiative neutron capture cross sections are very important in the field of basic physics research and nuclear device R&D. The Back-n white neutron beam line of China Spallation Neutron Source (CSNS) is the first spallation neutron beam line in China. On

Improved Fe ii Emission-line Models for AGNs Using New Atomic Data Sets [PDF]
, 2020 Understanding the Fe II emission from active galactic nuclei (AGNs) has been a grand challenge for many decades. The rewards from understanding the AGN spectra would be immense, involving both quasar classification schemes such as “Eigenvector 1” and ...

Experimental spectrum averaged cross sections (SACS) in 252Cf(sf) neutron field and its impact on the evaluation of neutron standards [PDF]
EPJ Web of Conferences, 2023 A new evaluation of spectrum averaged cross sections (SACS) of 235U, 238U, and 239Pu measured in the 252Cf(sf) reference neutron field is presented and found to be consistent with the original Mannhart SACS evaluation in IRDF-2002.

The systematics of neutron reaction cross sections [PDF]
EPJ Web of Conferences, 2020 The parameterized theoretical formulae of excitation functions for (n, 2n) and (n, γ) reactions have been established, and for (n,tot), (n,non), (n,3n), (n,p), (n,d), (n,t), (n,3 He) and (n,α) have been recommended.

ATOMIC DATA: DIVISION XII / COMMISSION 14 / WORKING GROUP ATOMIC DATA [PDF]
Proceedings of the International Astronomical Union, 2011 This report summarizes laboratory measurements of atomic wavelengths, energy levels, hyperfine and isotope structure, energy level lifetimes, and oscillator strengths. Theoretical calculations of lifetimes and oscillator strengths are also included. The bibliography is limited to species of astrophysical interest.
