Scattering length of the helium-atom–helium-dimer collision
Scattering length of the helium-atom–helium-dimer collision
We present our recent results on the scattering length of $^{4}\mathrm{He}\ensuremath{-}^{4}\mathrm{He}_{2}$ 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 …
