It is shown that transverse momentum conservation in the three-source Fái and Randrup statistical model does not explain the collective azimuthal alignment as observed in heavy-ion collisions at Bevalac energies.

Phonon Absorption

We investigate the effects of short range correlations on nucleon emission in peripheral relativistic heavy ion collisions, following an idea originally proposed by Feshbach and Zabek. Expressions for one- and two-nucleon emission cross sections are derived and calculations for typical heavy ion systems are performed. We show that momentum conservation in the phonon absorption process leads to pronounced ridges in the quadruple-differential cross section for two-nucleon emission. We suggest that the presence of such ridges in future exclusive experiments should be considered as a signature of correlated emission of a nucleon pair.
