氦原子与氦二聚体碰撞的散射长度

Scattering length of the helium atom - helium dimer collision

Elena A. Kolganova, Alexander K. Motovilov, Werner Sandhas

摘要:

本文介绍了我们最近对^4He-^4He_2碰撞散射长度的研究结果。这些调查的基础上的硬核版本的Faddeev微分方程。与我们以前计算的相同数量相比,采用了更精细的网格,提供了约10%的改进。我们的结果进行了比较与其他从头算,并与模型计算。

英文摘要:

We present our recent results on the scattering length of ^4He-^4He_2 collisions. These investigations are based on the hard-core version of the Faddeev differential equations. As compared to our previous calculations of the same quantity, a much more refined grid is employed, providing an improvement of about 10%. Our results are compared with other ab initio, and with model calculations.
