Various attempts have been made to describe the heavy-ion fusion excitation functions across
a wide energy region. The Wong formula includes the e↵ects of a quantum mechanical tunneling
through the Coulomb barrier and can reproduce the excitation function at the range larger
than 0.1 mb. The beauty of the Wong formula lies in its simple, analytical form with only
three parameters, while other more sophisticated theoretical models calculate the fusion cross
sections with numerical technology. Here We discuss two formulas, which keep the simple,
analytical forms, and have significantly performance across the whole energy region.
