A high statistics sample of photoproduced charm particles from the FOCUS (E831) experiment at Fermilab has been used to measure the D 0 and D + lifetimes. Using about 210 000 D 0 and 110 000 D + events we obtained the following values: 409.6±1.1 (statistical)±1.5 (systematic) fs for D 0 and 1039.4±4.3 (statistical)±7.0 (systematic) fs for D + .
