Radial Flow in the Interaction of Relativistic Deuterons with a Gold Target

The kinetic energy spectra of intermediate mass fragments (IMF) has been studied for 4.4 GeV d + Au collisions at the Dubna Nuclotron with the 4π detector array FASA. Experimental kinetic energy spectra were compared to that obtained by the multi-body Coulomb trajectory calculations with the initial break-up conditions given by the combined model INC + SMM. It was found good agreement of measured and calculated kinetic energy spectra including a radial flow.
