Title: | Integral and differential elastic collision cross-sections for low-energy Ar+ ions with neutral Ar atoms | Authors: | Barata, J. A. S. | Keywords: | Elastic scattering; Symmetric charge transfer; Intermolecular potentials | Issue Date: | 2007 | Citation: | Nuclear Instruments and Methods in Physics Research Section A: Accelerators, Spectrometers, Detectors and Associated Equipment. 580:1 (2007) 14-17 | Abstract: | Integral and differential elastic collision cross-sections for Ar+ ions with neutral Ar atoms are calculated using modified Tang and Toennies ion-atom interaction potential models, TTIA and TTIA-wb, to describe experimental spectroscopic data for the Ar2+ molecular ion, and the phase shifts are calculated by the JWKB approximation. Results are presented for center-of-mass energies in the 1 meV to 10 eV range. In our calculations, the effects of the spin-orbit interaction are included through a semi-empirical model. The results obtained agree with the scarce data available in the scientific literature. | URI: | https://hdl.handle.net/10316/4352 | DOI: | 10.1016/j.nima.2007.05.012 | Rights: | openAccess |
