Irradiation of nuclear emulsions in relativistic beams of He-6 and H-3 nuclei

Using a Li-6 nucleus beam extracted from the JINR Synchrophasotron at momentum 2.67A GeV/c a secondary beam was produced with a composition of 1% of He-6 and 99% of H-3 nuclei. Preliminary results on the features of nucleus-nucleus interactions of He-6 nuclei and charge exchange (CE) of H-3 nucleus are presented. Interactions of He-6 nucleus external neutrons with emulsion nuclei as well as a coherent stripping of He-6 nucleus external neutrons are observed. A mean range of H-3 nuclei to inelastic interactions in the BR-2 type emulsion is equal to 23.$\pm$3.0 cm. A mean range in emulsion for a nuclear CE process H-3 to He-3 is equal to 40$\pm$16 m. The CE cross-sections with a charged meson production or without it are approximately equal. The CE cross-section with excitation of a target nucleus exceeds the one without excitation. The mean transverse momentum of He-3 nuclei is equal to 0.16$\pm$0.03 GeV/c.

Similarity of multifragmentation of Au and Kr residual nucleus

Experimental data on multi-fragmentation of residual krypton nuclei created in the interactions of the krypton nuclei with photoemulsion nuclei at the energy of 0.9 GeV per nucleon are presented in a comparison with the analogous data on fragmentation of gold residual nuclei at the energy of 10.7 GeV/nucleon. It is shown for the first time that there are two regimes of nuclear multifragmentation: the former is when less than one-half of nucleons of projectile nucleus are knocked out, the latter is when more than one-half of nucleons are knocked out. Residual nuclei with closed masses created at different reactions are fragmenting practically simultaneously when more than one-half of nucleons of original nuclei are knocked out. The evidence of existence of a radial flow of the spectator fragment at the decay of residual krypton nuclei is found.
