S. Gandolfi, F. Pederiva, S. Fantoni, K. E. Schmidt

摘要:

在固定相近似下,采用辅助场扩散蒙特卡罗方法和包含张量力的Argonne v6'相互作用,计算了~ 4 He,~ 8He,~(16)O和~(40)Ca的基态能量.我们的轻核结果的格林函数蒙特卡罗计算的比较表明,我们的方法的准确性为开壳层和闭壳层核。我们还将其应用到16 O和40 Ca表明,量子蒙特卡罗方法现在适用于更大的核。

英文摘要:

We calculate the ground-state energy of 4He, 8He, 16O, and 40Ca using the auxiliary field diffusion Monte Carlo method in the fixed phase approximation and the Argonne v6' interaction which includes a tensor force. Comparison of our light nuclei results to those of Green's function Monte Carlo calculations shows the accuracy of our method for both open and closed shell nuclei. We also apply it to 16O and 40Ca to show that quantum Monte Carlo methods are now applicable to larger nuclei.
