Collision strengths for electron-impact of fine-structure level excitation within the ground term of Ne$^{+}$ and Ne$^{2+}$ are calculated using the Breit-Pauli, Intermediate Coupling Frame Transformation, and DARC $R$-matrix methods. Maxwellian-averaged effective collision strengths and excitation rate coefficient qij are presented for each. The application of the current calculations is to very low temperature astrophysical plasmas, thus we examine the sensitivity of the effective collision…

Fine-structure Excitation of Ne+ in Collision with Atomic Hydrogen
Fine-structure line emission from [Ne ii] is observed in the infrared (12.81 μm) and could serve as a diagnostic of X-ray irradiation in protoplanetary disks. [Ne ii] emission may also trace the disk
Effect of plasma screening on electron impact excitation and ionization of Fe16+ in a dense environment
Electron impact excitation and ionization with atoms and ions within a dense plasma are fundamental microscopic processes that determine the ionization balance, physical properties (such as
