Effective collision strengths for Ni III
Recent JWST observations of the Type Ia supernova (SN Ia) 2021aefx in the nebular phase have paved the way for late-time studies covering the full optical to mid-infrared (MIR)... -
Photoionization of the CH radical
The primary motivation of this paper is to provide accurate data for the photoionization of the CH radical, including absolute total photoionization cross section, partial cross... -
Tests of shock chemistry in IC 443G
The present study improves the computations of the collisional excitation rates by Green & Chapman (1978) for CS-H2; and by Bieniek & Green (1981) for SiO-H2. Part of... -
Collisional Excitation Rates of Formaldehyde
Earlier calculations for rotational excitation of formaldehyde H2CO collisions with He atoms are extended to include the 81 lowest rotational levels and kinetic temperatures to... -
Levels and rate coefficients of the Fe-L
A major challenge in X-ray spectral modeling is the Fe-L spectrum, which is basically a complex assembly of n>=3 to n=2 transitions of Fe ions in different ionization states,...
