TITLE=/ Effects of nuclear deformation on fusion probability in the
reactions of 82Se+natCe and 76Ge+150Nd near the Coulomb
barrier /;
PURPOSE=/ To test the supposition that the 76Ge+150Nd system
exhibits larger fusion probability than the system
consisting of spherical colliding nuclei whose Z1Z2 value is
close to that of 76Ge+150Nd /;
