Mean lifetimes of 22 bound levels and upper lifetime limits of four more levels in 32P below an excitation energy of 6.4 MeV were deduced from the Doppler-shift attenuation of γ rays produced in the inverse reaction 2H(31P,pγ). Of these 26 levels, the lifetimes of six levels are reported here for the first time. The low-lying portion of the level scheme, the level lifetimes, and the γ-ray branchings and reduced transition probabilities have been compared with shell-model predictions. The overall agreement is reasonably good.
