Theoretical oscillator strengths for the NI and OI resonance transitions

We report results from the first many-body calculations of the important oscillator strengths of the resonance lines NI $\text{1s}{}^2\text{2s}{}^2\text{2p}{}^3{}^4\text{S°?is}{}^2\text{2s}{}^2\text{2p}{}^2\text{3s}{}^4\text{P(λ=1200}\text{A}\text{?}\text{), 1s}{}^2\text{p}{}^2\text{3d}{}^4\text{P(λ=953}\text{A}\text{?}\text{)}$ and OI $\text{1s}{}^2\text{2s}{}^2\text{2s}{}^2\text{2p}{}^4{}^3\text{P ?1s}{}^2\text{2s}{}^2\text{2p}{}^3\text{3s}{}^3\text{S°(λ = 1304}\text{A}\text{?}\text{)}$. Our values are: $\text{?(1200)=0·271; ?(1304)=0·047; ?(953)= ·082}$. The first two are in excellent agreement with recent lifetime and absorption measurements and thus the existing discrepancy between theory and experiment is resolved. The third number constitutes the only available result for this transition.
