Sažetak
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/c2 (0<p_t<2.0 GeV/c) for the 4% most central collisions. An exponential fit gives an inverse slope T_d=(450ą30) MeV and a yield dN_d/dy=0.34ą0.03. The coalescence factor B2(m_t=m_0)=(3.5ą1.0)ˇ10^4 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.
