Abstract

We present our recent results on the scattering length of ⁴He\ensuremath-⁴He₂ 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 model calculations.
