“…As reported in the introduction, for similar reactions, in [3] the sticking limit was assumed to be reached, whereas in I-4] authors disagree with this assignment showing that both sticking and rolling configurations give M r higher than the experimental findings. To solve this controversy, the mean gamma-ray multiplicity was determined by means of the code CASCADE following the deexcitation of the two primary fragments produced in the observed deep inelastic processes.…”

“…In the present paper we investigate on the gamma-ray multiplicity behavior in the reaction2SSi+64Ni at 163.8 MeV with the aim to solve the contradiction between [1][2][3] and [4]. We will also integrate previous work done at lower energy (143 MeV) on the same reaction [1][2][3][4][5][6]7], where the evidence of a purely statistical gammadecay of nuclei formed in deep inelastic reactions and a strong non-statistical ):-emission in the quasi-elastic region was found.…”

Abstract. The 28Si + 64Ni reaction at 163.8 MeV incident energy is studied by measuring in coincidence 7-rays and charged particles identified from Z=2 to Z=16. The transition from quasi-elastic to more damped reactions is observed when the difference between the detected charge and the projectile one is increased. The strong influence of the particle decay on the measured ):-ray multiplicity is evidenced with the help of the statistical model computer code CASCADE. Dissipative events are well described in the rolling limit with excitation energy equally shared between the fragments. The overall agreement is lost for the fragments with the projectile charge which show a small value of the 7-multiplicity even for dissipative events. This is probably connected with the previously observed non statistical behavior of gamma rays emitted in coincidence with projectile-like fragments. In the alpha-spectrum measured in coincidence with gamma-rays, the deexcitation of fused systems is clearly separated from in flight emission of deep inelastic fragments. The low measured gamma-ray multiplicity for fusion events is qualitatively explained taking into account the effect of alpha-emission in the statistical decay.
