$^{40}$ Ca+ $^{96}$ Zr熔合反应的修正分析

Revised analysis of $^{40}$Ca+$^{96}$Zr fusion reactions

H. Esbensen, G. Montagnoli, A. M. Stefanini

摘要:

$^{40}$ Ca+ $^{96}$ Zr的融合数据进行了分析,耦合通道的计算是基于一个标准的伍兹-撒克逊潜在的,包括耦合到多声子激发和传输通道。耦合到多声子激发是在以前的工作中使用的相同。传递耦合器被校准以再现测量的中子传递数据。这种类型的计算对融合数据的拟合较差。然而,通过将传递联轴器与$\sqrt{2}$相乘,可以获得极好的配合。转移强度的标度应该模拟中子和质子转移的联合效应,计算的单核子和双核子转移截面确实与测量的截面相当一致。

英文摘要:

Fusion data for $^{40}$Ca+$^{96}$Zr are analyzed by coupled-channels calculations that are based on a standard Woods-Saxon potential and include couplings to multiphonon excitations and transfer channels. The couplings to multiphonon excitations are the same as used in a previous work. The transfer couplings are calibrated to reproduce the measured neutron transfer data. This type of calculation gives a poor fit to the fusion data. However, by multiplying the transfer couplings with a $\sqrt{2}$ one obtains an excellent fit. The scaling of the transfer strengths is supposed to simulate the combined effect of neutron and proton transfer, and the calculated one- and two-nucleon transfer cross sections are indeed in reasonable agreement with the measured cross sections.
