New data for the O16(+,2p) reaction at T=165 MeV are presented. Significant differences with previously published data are discussed. It is found that below 20 MeV excitation approximately 14% of the total absorption cross section is due to a two-nucleon mechanism. Evidence for direct two-nucleon absorption at higher excitation energy is also presented. Including estimates for final state interactions, the present results suggest that about 50% of the abosrption cross section is due to two-nucleon processes.
