%0 Journal Article %T Reconstruction of the Proton Source in Relativistic Heavy Ion Collisions %A Alberto Polleri %A Raffaele Mattiello %A Igor Mishustin %A Jakob Bondorf %J Physics %D 1999 %I arXiv %R 10.1016/S0375-9474(99)85063-5 %X We describe a direct method to reconstruct the transverse proton source formed in a relativistic heavy ion collision, making use of experimentally measured proton and deuteron spectra and assuming that deuterons are formed via two-nucleon coalescence. We show that an ambiguity with respect to the source temperature still persists and we indicate a possible solution to the problem. %U http://arxiv.org/abs/nucl-th/9907066v1
