Structure Calculations in Nd III and U III Relevant for Kilonovae Modelling
Atoms, 2022 The detection of gravitational waves and electromagnetic signals from the neutron star merger GW170817 has provided evidence that these astrophysical events are sites where the r-process nucleosynthesis operates.

Atomic Data and Nuclear Data Tables, 2012 Abstract The electric dipole oscillator strengths for lines between some singlet and triplet levels have been calculated using the weakest bound electron potential model theory and the quantum defect orbital theory for Be I. In the calculations both multiplet and fine structure transitions are studied.

Statistics of Oscillator Strengths in Chaotic Systems
, 1995 The statistical description of oscillator strengths for systems like hydrogen in a magnetic field is developed by using the supermatrix nonlinear $\sigma$-model. The correlator of oscillator strengths is found to have a universal parametric and frequency

Laser-Induced Breakdown Spectroscopy for Determination of Spectral Fundamental Parameters
Applied Sciences, 2020 In this review, we report and critically discuss the application of LIBS for the determination of plasma-emission fundamental parameters, such as transition probabilities, oscillator strengths, Stark broadening and shifts, of the emission lines in the ...
