摘要：

An accurate numerical finite-element method (FEM) solution of the three-body Coulomb problem with two equal masses is presented. The application of the FEM to systems with mass ratios ranging from 1836 to 1/1836 yields upper bounds for energy eigenvalues to a precision in the range of 10(-11)-10(-9) a.u. Expectation values for different operators are computed and discussed.
