Abstract

The invariant cross section as a function of transverse momentum for antideuterons produced in 158A GeV/c per nucleon Pb + Pb central collisions has been measured by the NA44 experiment at CERN. This measurement, together with a measurement of antiprotons, allows for the determination of the antideuteron coalescence parameter. The extracted coalescence radius is found to agree with the deuteron coalescence radius and radii determined from two particle correlations.
