In this paper, we report a detailed study on the de-excitation of the ⁴⁶Ti compound nucleus populated by means of four different reactions: ¹⁶O + ³⁰Si at 7 and 8 AMeV, ¹⁸O + ²⁸Si at 7 AMeV and ¹⁹F + ²⁷Al at 7 AMeV. The GARFIELD detection array was used to measure the light charged particles and the heavy fragments emitted. This setup covers a large fraction of the solid angle with high-granularity. Complete events are chosen through total charge (Z _TOT = 22) detection. Fusion-evaporation events are selected based on the condition that only one heavy fragment is detected in coincidence with the light charged particles. The analysis of global observables, such as charge distribution and light charged particle multiplicities, is compatible with the formation of a thermalized compound nucleus for all the four reactions. Nevertheless, an enhanced emission of α-particles with respect to a pure statistical picture is observed at very forward angles (<20). This enhancement is mainly visible in the even-Z residue exit channels populated through the emission of only α-particles.

在本文中，我们报告了通过四种不同反应填充⁴⁶ Ti 复合核的去激发的详细研究：7 AMeV 和 8 AMeV 下的¹⁶ O + ³⁰ Si，7 AMeV 和¹⁹ F 下的¹⁸ O + ²⁸ Si + ²⁷ Al，7 AMeV。GARFIELD 检测阵列用于测量发射的轻带电粒子和重碎片。这种设置覆盖了大部分具有高粒度的立体角。通过总费用（Z _TOT = 22) 检测。聚变蒸发事件是根据只有一个重碎片与轻带电粒子同时被检测到的条件来选择的。全局观测值的分析，例如电荷分布和轻带电粒子的多样性，与所有四个反应的热化复合核的形成相兼容。然而，相对于纯统计图片，在非常前角 (<20) 处观察到α粒子的增强发射。这种增强主要在通过仅发射α粒子而填充的偶数 Z 残留出口通道中可见。
