Three-body nonadditive interaction energies in the helium trimer are calculated by the complete fourth-order Mlaller-Plesset perturbation theory with large basis sets including bond functions. It is shown that the three-body energy can be easily converged to the complete basis set limit only if the
Highly correlated calculations of the collinear, symmetric break-up of helium trimer ions are carried out using an MRD-CI expansion and over a broad range of fragment relative distances. The general features of the lower roots of Xg, ~o, IIg and IIu symmetries are analysed in relation to recent expe
