The P II inter-system multiplet, at nm and 219.556nm, have been observed in emission from a low-pressure inductively-coupled plasma source. The measured branching ratio, , is in agreement with recent ab initio calculations. Absolute transition probabilities, s-1 and s-1, are determined by combining the measured branching ratio with the previously measured lifetime of the metastable level.
