The structure of a weakly bound ionic trimer: Calculations for the 4He2H- complex

摘要

The structure of the bound states of a very floppy trimeric complex in its ground electronic state, the 4He2H- complex, was examined by using both Jacobi coordinates within a DVR representation and pair coordinates with a DGF expansion. Assuming a pairwise form of the overall PES, focus was on the J=O situation. Results show that the 4He2H- complex is very unlikely to show the presence of Efimov-type states. © 2001 American Institute of Physics
