摘要

讨论了耦合通道对40Ca + 192Os、40Ca + 194Pt和48Ca + 197Au体系重离子聚变反应的影响。讨论了熔合截面σfus、熔合势垒分布Dfus和熔合概率Pfus。采用数值三点法、五点法和王氏法计算聚变势垒分布。使用CCFULL代码进行全量子耦合信道计算，并与现有实验数据进行比较。不耦合和耦合效应情况下的χ 2值清楚地表明，本文的计算与实验结果一致。

Enhanced calculations of fusion barrier distribution for heavy-ion fusion reactions using Wong formula

The effects of coupled-channels in heavy-ion fusion reaction for the system 40Ca + 192Os, 40Ca + 194Pt, and 48Ca + 197Au are discussed. The fusion cross-section σfus, the fusion barrier distribution Dfus and fusion probability Pfus are also discussed. The fusion barrier distribution is calculated using numerical three point, five point and Wong methods. Full quantum coupled-channels calculations are performed using CCFULL code with all order coupling to compare and with available experimental data. The χ² values for the case of no-coupling and coupling effects included shows clearly that the present calculations are in agreement with the experimental.

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.
