Abstract
Two-proton coincidences at very small relative moments were measured i n the reaction Xe-129 + Ti-48 at 45 MeV/nucleon using the SPEG spectro meter at GANIL. From the experimental correlation function, a precise value of the lifetime tau(0) = (3.90 +/- 0.15) 10(-21)s is extracted. Applying three angular cuts on the correlation function, a signature o f directional effects is observed and a value of the particle source v elocity nu(s) = (0.27 +/- 0.03)c is deduced in case of a sequential eq uilibrium emission.
