Subject to the assumption that sub-barrier fusion is described by an effective one-dimensional energy-independent local potential barrier, the Jeffreys-Wentzel-Kramers-Brillouin approximation for the fusion cross sections is inverted to determine this effective potential. Potential barriers, with their associated experimental errors, are presented for /sup 13/C+ /sup 13/C and /sup 40/Ca+ /sup 40/Ca, and the assumption of a local effective potential is shown to be inadequate for /sup 64/Ni+ /sup 64/Ni.
