摘要:

在双折叠模型(DFM)下,分析了270 MeV ~ 3 He粒子在~(90)Zr,~(116)Sn和~(208)Pb中的弹性和非弹性散射实验数据.利用靶核的费米密度分布(FDD)得到了不同幂次的实势。将DF结果引入到修正的DWUCK 4程序中,计算了弹性和非弹性散射截面。两种选择的潜力形状因子:伍兹撒克逊(WS)和伍兹撒克逊平方(WS 2)的真正的潜力,而虚部被视为唯象伍兹撒克逊(PWS)和唯象伍兹撒克逊平方(PWS 2)。这种比较提供了有关计算中使用的模型的相似性和差异的信息。

英文摘要:

The experimental data on elastic and inelastic scattering of 270 MeV 3He particles to several low lying states in 90Zr, 116Sn and 208Pb are analyzed within the double folding model (DFM). Fermi density distribution (FDD) of target nuclei is used to obtain real potentials with different powers. DF results are introduced into modified DWUCK4 code to calculate the elastic and inelastic scattering cross sections. Two choices of potentials form factors; Woods Saxon (WS) and Woods Saxon Squared (WS2) for real potential are used, while the imaginary part is taken as phenomenological Woods Saxon (PWS) and phenomenological Woods Saxon Squared (PWS2). This comparison provides information about the similarities and differences of the models used in calculations.
