Abstract

This paper presents a fortran program to solve diverse few-body problems with the stochastic variational method. Depending on the available computational resources the program is applicable for $N = 2 - 3 - 4 - 5 - 6 - ...$ -body systems with $L = 0$ total orbital momentum. The solution with the stochastic variational method is ``automatic'' and universal. One defines the system (number of particles, masses, symmetry, interaction, etc. ) and the program finds the ground state energy and wave function. The examples include nuclear (alpha particle: four-body, $^{6}$ He: six-body), atomic (td $μ^{-}$ and $e^{+} e^{-} e^{+} e^{-}$ ) and subnuclear (the nucleon and the delta in a nonrelativistic quark model) systems. The solutions are accurate for excited states as well, and even the Efimov-states can be studied. The program is available from the author (e-mail:[email protected]).
