The sub-barrier fusion excitation functions are measured for the first time for the system {sup 7}Li+ {sup 28}Si by the characteristic {gamma}-ray method in the energy range E{sub lab}=7-11.5 MeV. The results show an enhancement, below the barrier, by about a factor of two when compared with the one-dimensional barrier penetration (1D BPM) model. Introduction of coupling with the rotational 2{sup +} state (1.779 MeV) of the target improves the fit somewhat, but still an enhancement of about 25-40% remains.
