关于12C+16O反应的三体出射道的研究
About Three-Body Exit Channel in the Reaction 12C+16O at EL(16O)=56MeV
【摘要】 我们用两个带电粒子符合方法研究了能量为56MeV的16O轰击12C的三体反应出射道,分别得到了两个不同的三体出射道:α1+α2+20Ne和p+α+23Na的反应Q值谱,两道之间的比为8:1,同时得到了α1+α2两维符合事件的投影谱,结果显示α+24Mg是α1+α2+20Ne出射道的主要中间过程。理论分析告诉我们,两体的两步连续衰变与剥裂机制的统计计算相加,满意地和实验能谱符合,但是,从运动学计算来说,8Be1st+20Ne*,然后8Be1st→α1+α2的连续衰变机制也是不能完全排除的。
【Abstract】 Three-body exit channel in the reaction 12C+16O at 56 MeV has been studied by using measurement of the coincidence between the two changed particles. The projected spectra of the coinsidence between the two α-particles shows that the channel α+24Mg is the main intermediate process of three-body exit channel α1+α2+ 20Ne in the reaction 12C+16O at 56MeV. The analysis of theoretical calculation showed that the sum of sequential decay and statistical break-up fit the experimental spectra satisfactorily.
