晕核碎裂过程中的动力学相对论效应

Dynamical Relativistic Effects in Breakup Processes of Halo Nuclei

Kazuyuki Ogata, C. A. Bertulani

摘要:

用连续-离散耦合道方法(CDCC)研究了弱束缚核在中能碰撞中的破裂。对于大的碰撞参量,应用Eikonal CDCC(E-CDCC)方法。详细研究了洛伦兹收缩对核子势和库仑势的影响。这种效应倾向于显著地增加截面。我们还表明,对于松散束缚的核,所谓的近场的贡献是很小的,可以忽略不计。

英文摘要:

The continuum-discretized coupled-channels (CDCC) method is used to study the breakup of weakly-bound nuclei at intermediate energies collisions. For large impact parameters, the Eikonal CDCC (E-CDCC) method was applied. The effects of Lorentz contraction on the nuclear and Coulomb potentials have been investigated in details. Such effects tend to increase cross sections appreciably. We also show that, for loosely-bound nuclei, the contribution of the so-called close field is small and can be neglected.
