The He2−Ne system with the combination of the isotopes of helium ( He3 and He4) is used in structure calculations. Three-body channel functions and adiabatic potential functions have been calculated using the B-spline method. We use these channel functions in the slow variable discretization method to calculate the three-body bound states of the He2−Ne system. Using this method, two bound states for the 4He2−20Ne system and one bound state for each of the He4−He3−Ne20 and He32−Ne20 systems have been found. The geometry of the trimer is also ...
