热核的衰变动力学研究

在Vlasov框架下讨论了高温、高压缩核物质的动力学演化过程.通过研究得出,初始过程对碎裂的影响很大,这里密度的影响比热激发能的影响更大.在相同的初始条件下,不可压缩系数对碎裂过程影响很大,即热核在硬势的平均场中比在软势的平均场中更易裂开

Study on the Decay Dynamics of Hot Nuclei

With in the frameworu of the three-dimensional Vlasov equation,the dynamical evolution of highly compressed nuclei with high thermal excitation energy has been discussed. The distributions of particles in the space are uniform, while in the momentum space are Woods-Saxon distribution. The effects of initial conditions, temperature parameter and density, on the hot decay are great. The effect of the density on the hot decay is more important than the temperature parameter. For the same initial condition,the hot nuclei is more likely to decay in the hard potential than in the soft potential.
