“…1(a) and (b) respectively. Furthermore, the calculated eigenchannel parameters in 2-channel energy region smoothly connect with those in 8-channel energy region 23 . Therefore one only needs to calculate the short range reaction matrices (i.e., short range scattering matrices) at a few energy grids for entire energy regions.…”

“…It would take greater efforts to scan all these resonant structures with a much finer energy grid. The calculated τ ρ are equivalent to effective eigen-quantum-defects obtained from MQDT procedure 23 based on scattering matrices from full physical channel calculations. For the multi-thresholds problem shown in this work, we proposed a pro j ected h igh dimensional qu an tum-defect g raph (symmetri z ed), i.e JHANGZ plot, as an extension of Lu-Fano plot for multi-thresholds problems (more than two) to semi-analytically and graphically calculate all discrete levels without missing any one.…”

“…Based on analytical continuation properties of short-range scattering matrices, we have developed the relativistic eigenchannel R-matrix method (R-R-eigen code) [8][9][10][11][12][13][14], which has been successfully applied for many atomic processes, such as electron impact excitations [8,9], photoionizations [10,11,14], etc. In this method, we first calculate short-range scattering matrices, i.e., physical parameters associated with the multichannel quantum defect theory (MQDT) [15][16][17][18][19][20][21], and related wave functions for both discrete and continuous energy regions of interest.…”
