MANY-BODY COULOMB PERTURBATION OF AZIMUTHAL ALPHA-ALPHA CORRELATIONS

The perturbation of azimuthal alpha-alpha correlations by many-body Co ulomb interactions with other emitted particles is investigated. Indiv idual emissions are simulated by modeling instantaneous emission from the surface of a hot rotating gas. Upon emission, the particle traject ories are calculated by means of classical calculations which incorpor ate the many-body Coulomb interaction between the emitted particles an d the emitting source. For high-multiplicity events, the initial azimu thal correlation between emitted cu particles can be attenuated by fin al-state Coulomb interactions. The effect is most pronounced for cu pa rticles emitted close to the barrier, but it appears of ruiner importa nce for ct particles emitted at large relative angles and at energies well above the Coulomb barrier.
