Topology of Si-28 fragmentation at 14.6 A GeV in emulsion nuclei is given.
In all events, the charge of each projectile fragment is measured. We repor
t the measurements on total and some partial reactions cross sections of 28
Si interactions. The data for Z greater than or equal to 6 can be qualitati
vely described by a statistical percolation model. The results are discusse
d and compared with those obtained from Si-28 at 3.7 A GeV and S-32 at 200
A GeV.
