摘要

本文介绍了利用XTU串联加速器的28Si光束，在意大利国家实验室进行的12C + 28Si聚变截面测量的初步结果。我们利用γ-阵列AGATA和两个环形DSSD Si探测器的组合装置，通过提示γ射线和从复合核蒸发的轻带电粒子（p, α）之间的重合来识别和计数聚变蒸发事件。通过脉冲形状分析，利用上升时间和能量信号来识别光粒子。在50-29.5 MeV范围内测量了五束能量。

Fusion dynamics far below the barrier for 12C + 28Si

We present preliminary results of fusion cross section measurements for ¹²C + ²⁸Si, performed at the INFN-Laboratori Nazionali di Legnaro, using ²⁸Si beams from the XTU Tandem accelerator. We have used the combined set-up of the γ-array AGATA and two annular DSSD Si detectors to identify and count the fusion evaporation events by coincidences between the prompt γ-rays and the light charged particles (p, α) evaporated from the compound nucleus. The light particles have been identified through pulse shape analysis, using the rise time and the energy signals. Five beam energies have been measured in the range 50-29.5 MeV.
