Abstract We report in this paper energy positions of the ( 2pns ) 1 , 3 P ∘ and ( 2pnd ) 1 , 3 P ∘ Rydberg states ( n = 3 – 60 ) and resonance widths of the ( 2pns ) 1 P ∘ and ( 2pnd ) 1 P ∘ ( n = 20 ) members of these series of the B + ion. Calculations are performed in the framework of the screening-constant-by-unit-nuclear-charge method. Along all the series investigated, the quantum defect is almost constant up to n = 60 . The present results compare very well to available theoretical and experimental literature values up to n = 20 . The data presented in this work may be a useful guideline for investigators considering the photoionization spectrum of the B + ion.
