Abstract

With our relativistic eigenchannel R-matrix method R-R-Eigen, the physics parameters of Ne+ in multi channel quantum defect theory (MQDT) are calculated directly, such as eigenchannel quantum defects, transformation matrix etc al. Various physical quantities can then be derived from a straightforward application of the MQDT procedure. Using our proposed projected high dimensional quantum-defect graph (symmetrized) - a generalization of Lu-Fano plots, we can readily determine the accuracies of the calculated MQDT physical parameters (ie. scattering matrix) systematically against the experimental energy levels. Based on the analytical continuation property of short-range scattering matrix below and above threshold, the origin of each resonant peak observed in the experiment can be designated. there is possibility to adjust calculated total photoionization spectra to fit the experiment.
