The mean lifetimes of nine levels in 30P, between 3.7 and 4.7 MeV excitation energy, have been measured using the Doppler shift attenuation method. A limit has also been placed on the lifetime of one further level. Three of these lifetimes have not previously been measured, these are 40+or-30 fs, 180-50+60 fs and 185+or-15 fs for the 4225, 4298 and 4343 keV levels respectively. A doublet has been found at 4229.9+or-1.3 keV and 4234.5+or-1.8 keV where only a single level had been previously reported. The measured lifetimes give transition strengths which lead to spin assignments of 2+ and 3 for the 3834 and 3927 keV levels respectively.
