摘要:

我们在两个轻的重离子$^{12}$ C和$^{16}$ O之间进行了重离子辐射俘获反应,得到了$^{28}$ Si。本实验已进行低于库仑势垒能量,以减少相空间,并试图阐明结构的影响。获得的$γ$ -光谱显示了以前未观察到的强喂养的中间状态在这些能量约11兆电子伏。这个新的衰变分支并不完全由统计或半统计衰变的衰变分支所再现,并且可能意味着结构效应。辐射俘获截面提取的数据。

英文摘要:

We have performed a heavy ion radiative capture reaction between two light heavy ions, $^{12}$C and $^{16}$O, leading to $^{28}$Si. The present experiment has been performed below Coulomb barrier energies in order to reduce the phase space and to try to shed light on structural effects. Obtained $γ$-spectra display a previously unobserved strong feeding of intermediate states around 11 MeV at these energies. This new decay branch is not fully reproduced by statistical nor semi-statistical decay scenarii and may imply structural effects. Radiative capture cross-sections are extracted from the data.
