Electron-impact excitation cross-sections of Ne II using the B-Spline atomic R-Matrix code

Cross sectional data for electron collisions with neutral neon is relatively abundant [1,2] due to the increased use of neon gas in Low Temperature Plasma (LTP) applications such as analytical spectrometry [3]. However, limited data is available for electron-impact excitation of the Ne II ion despite its significance in astrophysical environments such as circumstellar and protoplanetary disks [4,5]. In this work, we seek to determine electron-impact excitation cross sections of singly-ionized Neon using the B-Spline atomic R-Matrix (BSR) suite of codes [6,7]. In particular, we will calculate electron-impact excitations for transitions from the 1s²2s²2p⁴nl and 1s²2s2p⁵nl states.  Additionally, relevant Ne II atomic structure data, which can be used as input for BSR calculations, will be made available on the AMOSGateway [8], where interested parties can perform their own cross-section calculations.
