Scientific paper

We report the observation of a pair of spin-forbidden resonance lines in singly-ionized phosphorus. These lines at λ _air = 2210Å and 2196Åare observed in emission from a low-pressure inductively-coupled helium plasma containing a small amount of evaporated P_4. These and other spin-forbidden lines in low-Z ions are of interest not only because of the suitability of such lines for astrophysical diagnostic purposes, but also because these lines have presented a substantial computational challenge to atomic theorists. Accurate experimental determination of oscillator strengths and lifetimes therefore provide an excellent test of the various computational approaches. Unfortunately, experimental challenges, such as the inherent weakness of spin-forbidden lines and the difficulty in making sources for several of the species of interest, have prevented many of the desired measurements from being made. We report on our progress toward the measurement of an accurate branching ratio for the 3s3p^3 ^5S_2 - 3s^23p^2 ^3P_2,1 spin-forbidden pair in P^+. The branching ratio, when obtained, can be combined with the previously measured ^5S2 lifetime(A.G. Calamai et al., Phys. Rev. A, 45), 2716 (1992). to yield absolute oscillator strengths for both lines.
