Session DH - High Energy Heavy Ion Collisions.
ORAL session, Thursday morning, October 18

We report an extension of the source imaging method for imaging full three-dimensional sources from three-dimensional charged pion correlations (i.e. in side-out-long coordinates). In this method, we expand the angular dependence of the source in spherical harmonics and represent the radial dependence of the source with Basis-splines. The imaging reduces to a least-square minimization problem where we may implement constraints and use other techniques to stabilize the inversion. We apply this method to simulated charged pion correlations and to experimental data. Because we explicitly account for the final-state interactions between the pair, we do not apply an ad-hoc Coulomb correction. This work was performed under the auspices of the U.S. Department of Energy by the University of California, Lawrence Livermore National Laboratory under Contract no. W-7405-Eng-48.
