Abstract

The effect of the breakup channel on fusion reactions of weakly bound systems by means of semi-classical and full quantum mechanical approaches has been discussed. The total fusion reaction cross-section σfus and the fusion barrier distribution Dfus for the systems 4He+64Zn, 6Li+208Pb and 7Li+24Mg have been calculated. The inclusion of the breakup channel enhances the calculations of the fusion cross-section markedly below the Coulomb barrier and hindrance above the Coulomb barrier in comparison to the experimental data. The semi-classical calculations agree reasonably with the full quantum mechanical treatment and they were able to reproduce the experimental data in details for the total fusion reaction cross-section σfus and the fusion barrier distribution Dfus.

裂变通道在轻核和弱束缚核的聚变反应中的作用

用半经典和全量子力学方法讨论了断裂通道对弱束缚体系核聚变反应的影响。计算了4He+64Zn、6Li+208Pb和7Li+24Mg体系的总熔合反应截面σfus和熔合势垒分布Dfus。与实验数据相比，分解通道的加入显著提高了库仑势垒以下的聚变截面计算和库仑势垒以上的阻挡计算。半经典计算与全量子力学处理基本一致，能较详细地再现聚变反应截面σfus和聚变势垒分布Dfus的实验数据。

期刊介绍： Today, nuclear reactors generate nearly one quarter of the electricity in nations representing two thirds of humanity, and other nuclear applications are integral to many aspects of the world economy. Nuclear fission remains an important option for meeting energy requirements and maintaining a balanced worldwide energy policy; with major countries expanding nuclear energy"s role and new countries poised to introduce it, the key issue is not whether the use of nuclear technology will grow worldwide, even if public opinion concerning safety, the economics of nuclear power, and waste disposal issues adversely affect the general acceptance of nuclear power, but whether it will grow fast enough to make a decisive contribution to the global imperative of sustainable development.
