Gasdynamic model of intermediate energy heavy ion collisions and high-energy particle emission

Emission of high-energy particles is investigated for cases of collision of heavy ions of intermediate energies in the framework of gasdynamic model. Nonequilibrium equation of state corresponding to fermi-ellipsoid is used in calculations. In the process of collision the smaller nucleus makes ''a tube of nuclear matter'' in the target nucleus. The process of nucleus colllision with the tube is performed in two stages: initial compression and the following relaxation. Results of calculations of compression degree on the collision energy for nucleon are presented, as well as maximum velocity in the process of system expansion for Brakner interaction and Skyrme interactiion. Spectra of neutrons in the 12C+158Gd reaction and proton spectra in the 16O+197Au reaction are calculated
