# Solution of few-body problems with the stochastic variational method I. Central forces with zero orbital momentum

## Description

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 examp... Title of program: FBS Catalogue Id: ADGF_v1_0 Nature of problem This computer code solves N = 2 - 3 - 4 - 5 - 6 -..-body problems. The number of particles, symmetry, interaction, etc. are input data and the program can solve various few-body problems. The examples include nuclear (alpha particle: four-body, 6He: six-body), atomic (tdmu- 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.
