Table 5: Resonance widths (Γ ) of doubly (2pnd) 1P° excited states of B+. The present MAOT results are compared to the Screening Constant by Unit Nuclear Charge (SCUNC) results of Sakho, et al. [7]; Multiconfiguration Relativistic Random-Phase Approximation (MCRRPA) computations of Hsiao, et al. [6]; Noniterative Eigenchannel R-Matrix (NER-M:) results of Kim and Manson [5]; R-matrix (R-M) calculations of Tully, et al. [4] and to the Advanced Light Source (ALS) experiments of Schippers, et al. [3]. The a (-b) (c) notation means a × 10-b and (c) indicates the uncertainties of the experimental widths given in parentheses. The results are expressed in eV.
