重离子聚变的时变性Hartree-Fock描述

Time-Depentent Hartree-Fock description of heavy ions fusion

Cédric Simenel, Benoît Avez

摘要:

在含时Hartree-Fock(TDHF)理论框架下,采用Skyrme相互作用和SLy 4d参数化,对重离子聚变进行了微观平均场描述.一个很好的协议与实验上的融合障碍的位置,各种总质量,质量不对称性和变形。16 O +208 Pb的激发函数在势垒以上被高估了约16%。在平均场动力学中,对独立粒子态的限制阻碍了对亚势垒熔合的描述。讨论了转移对熔合的影响。

英文摘要:

A microscopic mean-field description of heavy ions fusion is performed in the framework of the Time-Dependent Hartree-Fock (TDHF) theory using a Skyrme interaction with the SLy4d parametrization. A good agreement with experiments is obtained on the position of the fusion barriers for various total masses, mass asymmetries and deformations. The excitation function of the 16O+208Pb is overestimated by about 16% above the barrier. The restriction to an independent particles state in the mean-field dynamics prevents the description of sub-barrier fusion. Effect of transfer on fusion is discussed.
