Beschreibungen/Notizen

• Experimental results on deuteron emission from central Pb+Pb collisions ( E beam=158A GeV, fixed target), obtained by NA49 at the CERN SPS accelerator, are presented. The transverse mass m t distribution was measured near mid-rapidity (2.0< y<2.5) in the range of 0< m t − m 0<0.9 GeV/ c 2 (0< p t <2.0 GeV/ c) for the 4% most central collisions. An exponential fit gives an inverse slope T d =(450±30) MeV and a yield dN d / dy=0.34±0.03. The coalescence factor B 2( m t = m 0)=(3.5±1.0)·10 −4 GeV 2 and its m t -dependence are determined and discussed in terms of a model that includes the collective expansion of the source created in a collision. The derived Gaussian size parameter R G of the emission volume is consistent with earlier HBT results on the source of pion emission.
