摘要:

在加拿大温哥华的Triumf实验室,利用Dragon 0°光谱仪和相应的BGO阵列,研究了12 C +16 O共振辐射俘获反应在Elab = 15.4和21.4 MeV之间的5种轰击能量下的库仑势垒附近的情况。最值得注意的结果是以前未观察到的衰变路径通过28硅门口的能量约12兆电子伏的测量新的捕获截面。讨论了28 Si中特定的形变态从共振态的馈入,以及11 MeV附近1^+ T=1态的选择性馈入。

英文摘要:

The 12C+16O resonant radiative capture reaction has been studied at 5 bombarding energies between Elab = 15.4 and 21.4 MeV, around the Coulomb barrier, at the Triumf laboratory (Vancouver, Canada) using the Dragon 0° spectrometer and the associated BGO array. The most remarquable result is the previously unobserved decay path through 28Si doorway states of energies around 12 MeV leading to the measurement of new capture cross-sections. The feeding of specific, deformed states in 28Si from the resonances is discussed, as well as the selective feeding of 1^+ T=1 states around 11 MeV.
