Abstract In this Comment on the above‐mentioned paper by F. E. Harris, A. M. Frolov, and V. H. Smith, we briefly review our contributions to development of new methods for solution of the Coulomb four‐body problem. We show that our research group, headed by Professor T. K. Rebane, had a priority in using the fully correlated exponential basis for variational calculations of four‐body systems. We also draw attention to the fact that our group subsequently implemented a more advanced method, which uses highly efficient exponential‐trigonometric basis functions for solution of the same problem. © 2005 Wiley Periodicals, Inc.
