Ultracold scattering processes in three-atomic helium systems

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

We review results on scattering observables for ${}^4$He--${}^4$He${}_2$ and ${}^3$He--${}^4$He${}_2$ collisions. We also study the effect of varying the coupling constant of the atom-atom int…
