The interferometry: a technique of analysis of the dynamical correlations and collision evolution

The study of the correlations of the light particles is usually performed to determine the size and lifetime of the hot sources produced in the nuclear reactions. For studies of this type such sources are described rather simply without taking into account either their time evolution or the correlations between the space-time coordinates of the particle emission points and their momenta. Simulations performed using the transport model QMD are used to take into account dynamical correlations in the interferometry analysis. The two proton correlation function calculated in this way was compared with the experimental data. The simulations were realized for the case of 129 Xe + 48 Ti at 45 MeV/u. To estimate the importance of different dynamical effects on the correlation function several computations were carried out. When these dynamical correlations were taken into account, the proton-proton correlation function showed a significant structure around 20 MeV/c due to the strong interactions
