  We report lifetimes, branching fractions, and the resulting oscillator
strengths for transitions within the P II multiplet (3s^23p^2 ^3P - 3s^23p4s
^3P^o) at 1154 A. These beam-foil measurements represent the most comprehensive
and precise set currently available experimentally. Comparison with earlier
experimental and theoretical results is very good. Since Morton's most recent
compilation is based on the earlier body of results, phosphorus abundances for
interstellar material in our Galaxy and beyond derived from lambda 1154 do not
require any revision.
