Abstract: A FORTRAN package is programmed for non-relativistic limit and a coplanargeometry on PDP-11/34. The package is designed to provide users as many con-veniences as possible. Besides adopting man-machine interaction mode and settingnuclide mass file, there are still some other features which are, for examples, thefunctions of offering the initial values for some transcendental equations andevaluating all the kinematic variables in nuclear reactions at low energies of theform of T (p, 1)2, T (p, 12)3 and T (p, 12)34. All these make the users mucheasier to use the package.
