Very precise elastic cross sections have been measured in a very forward angular range (up to 1.6{degree} laboratory) for the {sup 12}C+{sup 12}C system at six energies not too far above the Coulomb barrier. From these data the symmetrized nuclear scattering amplitude {ital f}{sub {ital N}}{sup {ital s}}({theta}) for small angles and the total reaction cross section {sigma}{sub {ital R}} could be derived making use of the generalized optical theorem for charged particles. It was found that {vert bar}{ital f}{sub {ital N}}{sup {ital s}}(0){vert bar} exceeds zero significantly in all cases investigated. This means that a forward nuclear glory exists in the {sup 12}C+{sup 12}C scattering. This is the first time that evidence for a forward nuclear glory is deduced from experimental data.
