Identification of mechanisms in heavy ion reactions by measurement of angular correlations

Description

The identification of reaction mechanisms in light heavy-ion collisions has been performed within the framework of the three body kinematics, by means of angular correlation measurements. The 16O+27Al, 16+O+28Si and 10B+27Al reactions were investigated at Laboratory bombarding energies of 64 MeV, 64 and 48 MeV, respectively. Contributions of transfer-reemission and projectile sequential decay mechanisms were identified by the analysis of the relative kinetic energy of the final state components, excitation energies of the system at the intermediate stages, and also by means of fits to theoretical predictions for the angular correlations.

Abstract (Portuguese)

Atraves da uma analise baseada na cinematica de tres corpos, uma identificacao de mecanismos em reacoes entre ions pesados foi efetuada a partir da medida de correlacoes angulares. Foram estudados os istemas 16O+ 27Al, 16O + 28Si e 10B + 10B + 27Al nas energias de bombardeio de 64, 64 e 48 MeV, respectivamente. A partir de previsoes teoricas para as correlacoes angulares, da analise de espectros de energia cinetica do movimento relativo entre os constituintes do estado final e energia de excitacao dos nucleos intermediarios, constatamos a presenca dos mecanismos de transferencia seguida de evaporacao e decaimento sequencial do projetil.
