Abstract
Numerical techniques for the integration of the Schrödinger equation in imaginary time are investigated. Because the spatial dependence of the solution in the limit of large imaginary time is that of the ground state of the Hamiltonian, the method can be applied to bound states of quantum-mechanical three-body systems. Knowledge of the analytic dependence of the asymptotic form of the wavefunction on the trial eigenvalue is not required. In this paper, the first of a series, we have confined our attention to the problems arising from the imaginary time integration and reserve for a later date a discussion of the problems that are due to a multidimensional spatial grid.
