摘要:

在变形的靶核的密度分布中,考虑球形$λ= 0$和变形的$λ= 2$部分。在此基础上,得到了双重折叠微观核-核光学势的相应势部分$U_0$和$U^{(2)}_{int}$。然后,利用耦合道技术(ECIS)计算了$^{17}O$重离子在$2^{+}$集体激发态上的弹性和非弹性散射振幅.此外,在程函近似的绝热近似框架下,计算了相同的截面,其中非弹性振幅是$U^{(2)}_{int}$的线性函数。将所得结果与实验数据进行了比较,并讨论了它们在预测原子核形变参数方面的有效性。

英文摘要:

In the density distribution of a deformed target-nucleus, the spherical $λ= 0$ and the deformed $λ= 2$ parts were considered. On this basis, the corresponding potential parts $U_0$ and $U^{(2)}_{int}$ of a double -folding microscopic nucleus-nucleus optical potential are obtained. Then, for these potentials and by using the coupled-channel technique (ECIS), the elastic and inelastic amplitudes are calculated for $^{17}O$ heavy ion scattering on $2^{+}$ collective excited state of various target nuclei. Besides, the same cross-sections are calculated in the frame of an adiabatic approach of the eikonal approximation, where the inelastic amplitude is the linear function of $U^{(2)}_{int}$. Both the obtained results are compared with the experimental data, and also discuss their efficiency in predicting the deformation parameters of nuclei.
