非局域势的有效相互作用超球谐方法

The effective interaction hyperspherical harmonics method for non-local potentials

G. Orlandini, N. Barnea, W. Leidemann

摘要:

提出了一种适用于非局域势的有效相互作用超球谐函数(EIHH)方法。EIHH方法的本地相互作用的第一个简短的审查指出的问题的扩展到非本地的潜力。提出了一个可行的解决方案,并作为应用,结果的基态性质的4-和6-核子系统。人们发现,超球谐级数的收敛速度大大加快。通过洛伦兹变换方法的散射截面的应用前景进行了讨论。

英文摘要:

A different formulation of the effective interaction hyperspherical harmonics (EIHH) method, suitable for non-local potentials, is presented. The EIHH method for local interactions is first shortly reviewed to point out the problems of an extension to non-local potentials. A viable solution is proposed and, as an application, results on the ground-state properties of 4- and 6-nucleon systems are presented. One finds a substantial acceleration in the convergence rate of the hyperspherical harmonics series. Perspectives for an application to scattering cross sections, via the Lorentz transform method are discussed.
