D. Lacroix, M. Assie, S. Ayik, G. Hupin, J. A. Scarpaci, K. Washiyama

摘要:

发展了超越平均场的微观理论,包括核子对、介质中核子-核子碰撞以及单体观测量的初始涨落对核动力学的影响。这些理论被应用于核反应。对原子对在核破裂中的作用进行了讨论。通过随机平均场论引入集体变量零点运动的影响,不仅可以很好地描述单体观测量的平均演化,而且可以很好地描述涨落。在融合扩散系数以及在转移反应的质量分布估计。

英文摘要:

Microscopic theories beyond mean-field are developed to include pairing, in-medium nucleon-nucleon collisions as well as effects of initial fluctuations of one-body observables on nuclear dynamics. These theories are applied to nuclear reactions. The role of pairing on nuclear break-up is discussed. By including the effect of zero point motion of collective variables through a stochastic mean-field theory, not only average evolution of one-body observables are properly described but also fluctuations. Diffusion coefficients in fusion as well as mass distributions in transfer reactions are estimated.
