Triton-Triton Correlation and Emission Times in Intermediate Energy Nucleus-Nucleus Collisions

Triton-triton correlation functions have been measured for 40Ar+197Au collisions at E/A = 25 MeV. The anticorrelations at small relative momenta are observed and become more pronounced with the increasing total energy of two coincident tritons. Comparison with the three-body trajectory calculations indicates that the average emission times lie between 100 and 300 fm/c for tritons.
