Angular distributions of 7Li(7Li,t), (7Li,alpha) and (7Li,6He) reactions were measured for laboratory energies from 2 - 16 MeV. Exact finite range DWBA analyses were performed with the aim to identify contributions of direct processes and to investigate the applicability of DWBA to such few nucleon systems. It turned out that DWBA can be successfully applied to estimate differential and total cross sections of direct transfer processes in 7Li+7Li interaction. The direct mechanism was found to play a dominant role in most of these reactions but significant contributions of other, strongly energy dependent processes were also established. It is suggested that these processes might be due to isolated resonances superimposed on the backround of statistical fluctuations arising from interference of compound nucleus and direct transfer contributions.
A nucleation model analysis of neck emission yields in 124Sn+112,124Sn reactions at 26 MeV/nucleon
最近的分析实验三元裂变碎片产额使用核调节的统计平衡模型再现观察到的产额具有相当好的精度。在本工作中,同样的方法被应用到颈部发射在周边和中部周边124 Sn +112,124 Sn碰撞在26 A MeV。该模型能够合理地再现锂到硅同位素的产额与现实的时间和温度值。比较了由本数据得到的平衡常数与以前得到的242 Pu三裂变的平衡常数。
Study of 9Be+12C elastic scattering at energies near the Coulomb barrier
在这项工作中,角分布测量的弹性通道进行了9 Be +12 C反应在能量ELab=13.0,14.5,17.3,19.0和21.0 MeV,附近的库仑势垒。的数据进行了分析的框架内的双重折叠圣保罗潜力。实验的弹性散射角分布很好地描述了在所有测量的能量的前向角的光学势。然而,对于三个最高的能量,观察到增强的中间和向后的角度。这可以用弹性转移机制来解释。关键词:9 Be +12 C,弹性散射,圣保罗势。
