Analysis of fast and slow particles production from the interaction of 24Mg with emulsion nuclei at 4.5A GeV c

Abstract EN

The target fragmentation of emulsion nuclei in the interaction of 24Mg projectile at 4.5A GeV/c is investigated.

The rapidity and angular distributions of the emitted fragments (grey and black) are analyzed in terms of the statistical model.

The mean longitudinal velocities and the characteristics spectral velocities of the particle emitting system are determined.

The temperatures T of the emitting system for grey and black particles (60 and 6 MeV respectively) are found to be independent of the projectile mass number and target size.

The experimental range– energy distributions as well as the relationship between the energy and the rate of energy loss for both the grey and black particles can be described well by the outputs of a special computer program called SRIM.

The kinetic energy distributions of produced grey and black particles are presented in power law relations and agree well with the predictions of the cascade evaporation model.
