| 摘 要： | There can be found some notable discrepancies with regard to the resonance structures when R-matrix calculations from the Opacity Project and other sources are compared with recent absolute experimental measurements of Bizau et al [Astron.Astrophts.439 387(2005)] for B-like ions N2+,O3+ and F4+.We performed close-coupling calculations based on the R-matrix formalism for the photoionizations of ions mentioned above both for the ground states and first excited states in the near threshold regions.The present results are compared with experimental ones given by Bizau et al and earlier theoretical ones.Excellent agreement is obtained between our theoretical results and the experimental photoionization cross sections.The present calculations show a significant improvement over the previous theoretical results. |

| Abstract: | There can be found some notable discrepancies with regard to theresonance structures when R-matrix calculations from theOpacity Project and other sources are compared with recent absoluteexperimental measurements of Bizau et al [Astron.Astrophts. 439 387 (2005)] for B-like ions N2+,O3+ and F4+. We performed close-coupling calculationsbased on the R-matrix formalism for the photoionizations ofions mentioned above both for the ground states and first excitedstates in the near threshold regions. The present results arecompared with experimental ones given by Bizau et al andearlier theoretical ones. Excellent agreement is obtained betweenour theoretical results and the experimental photoionization crosssections. The present calculations show a significant improvementover the previous theoretical results. |
