Inversion formula for the internucleus potential using sub-barrier fusion cross sections


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 ^(13)C+^(13)C and ^(40)Ca+^(40)Ca, and the assumption of a local effective potential is shown to be inadequate for ^(64)Ni+^(64)Ni
