Angular distributions of light projectile fragments in deep inelastic Pb+Em interactions at 160 A GeV
The nuclear emulsion was exposed at CERN by the lead projectile at 160 A GeV. The angles between any pair of fragments with Z=2-4 have been measured in the emulsion plane for the events which did not contain heavy fragments. The constant characterizing the normal angle ( phi ) distribution of the fr...

| description | The nuclear emulsion was exposed at CERN by the lead projectile at 160 A GeV. The angles between any pair of fragments with Z=2-4 have been measured in the emulsion plane for the events which did not contain heavy fragments. The constant characterizing the normal angle ( phi ) distribution of the fragment momentum projection onto the emulsion plane with respect to initial projectile momentum p/sub 0/ is found to be sigma /sub phi /=(0.37+or-0.02) mrad. Corresponding value sigma /sub 0/=(121+or-6) MeV/c of nucleon momentum distribution in the lead nucleus coincides with that expected from Fermi momentum distribution for this nucleus. The peak in the pair-angle distribution of double-charged fragments, /sup 8/Be to 2 alpha , is presented for the region of small angles (<0.1 mrad). The fraction of alpha -particles coming from the decay of the ground state /sup 8/Be is found to be (13+or-2)601130f their whole number. (14 refs). |
