Περίληψη:

The composition of forward-going projectile spectator matter in
fixed-target Pb+Pb collisions at 158 A.GeV at the CERN SPS has been
studied as a function of centrality. The data were measured with the
NA49 veto calorimeter. We observe that forward-going spectator matter in
central collisions consists of 9 neutrons, 7 protons, and half a
deuteron on average. At large impact parameters most spectator nucleons
are bound in fragments. The relative resolution of the average impact
parameter derived from the measurement of spectator neutrons is roughly
19% in the range from zero to half maximum impact parameters.
